En væsentlig del af Astropy-projektet er konceptet »Affiliated Packages«. En tilknyttet pakke er en astronimi-relateret Pythonpakke, der ikke er en del af grundpakken for astropy, men har anmodet om at blive inkluderet som en del af Astropy-projektets fællesskab. Disse pakker udviser en interesse i Astropys formål ved at forbedre genbrug, samarbejde og grænsefladestandarder for Pythonpakkerne indenfor astronomi og astrofysisk.

Denne metapakke installerer alle tilknyttede pakker.

HEALPix er et akronym for Hierarchical Equal Area isoLatitude Pixelization af en sfære. Som antydet i navnet laver denne pixelization en underopdeling af en sfærisk overflade hvori hvert billedpunkt dækker det samme overfladerum som andre billedpunkter. Det bruges normalt til at lagre »all-sky« astronomiske billeder, mest kendt kort over den kosmiske mikrobølgebaggrund.

Dette er en HEALPix-pakke med BSD-licensen udviklet af Astropyprojektet og baseret på C-kode skrevet af Dustin Lang i astronomy.net.

Denne pakke tilbyder moduler for Python 3.

Dette modul kan vise, konfigurere og køre CPL-baserede opskrifter fra Python3. Inddata, kalibrering og uddata kan specificeres som FITS-filer eller som astropy fits-objekter i hukommelsen.

Common Pipeline Library (CPL) består af et sæt af ISO-C-biblioteker, som tilbyder et omfattende, effektivt og robust programværktøjssæt. Den udfører et grundlag for oprettelsen af automatiserede astronomiske datareduktionsopgaver.

En af funktionerne tilbudt af CPL'en er muligheden for at oprette algoritmer for datareduktion, som kører som udvidelsesmoduler (dynamiske biblioteker). Disse kaldes for »opskrifter« og er et af hovedaspekterne til udviklingsmiljøet for CPL-datareduktion.

Dask is a flexible parallel computing library for analytics, containing two components.

1. Dynamic task scheduling optimized for computation. This is similar to Airflow, Luigi, Celery, or Make, but optimized for interactive computational workloads.
2. "Big Data" collections like parallel arrays, dataframes, and lists that extend common interfaces like NumPy, Pandas, or Python iterators to larger-than-memory or distributed environments. These parallel collections run on top of the dynamic task schedulers.

This contains the Python 3 version.

The drms module provides an easy-to-use Python interface for accessing HMI, AIA and MDI data with Python. It uses the publicly accessible Joint Science Operations Center (JSOC) server by default, but can also be used with local NetDRMS sites.

The Helioseismic and Magnetic Imager (HMI) and the Atmospheric Imaging Assembly (AIA) are instruments aboard the Solar Dynamics Observatory (SDO) designed to study oscillations and the magnetic field at the solar surface. The Michelson Doppler Imager (MDI) is the predecessor to the current HMI and was launched aboard the Solar and Heliospheric Observatory (SOHO). HMI and MDI observe the full solar disk at 6173 Å with high resolution, while AIA is designed to study the solar corona.

Fitsio provides an easy to use object-oriented API including providing a Numpy interface to FITS files read from CFITSIO. It allows direct access to the columns of a FITS binary table which can be useful for reading large fits files. Compared to astropy.io.fits, this package is closer to the underlying cfitsio library.

Fitsio also exposes a microlanguage (implemented in CFITSIO) for making efficient SQL-like queries of tables (single tables only though–no joins or anything like that).

Ginga is a toolkit designed for building viewers for scientific image data in Python, visualizing 2D pixel data in numpy arrays. It can view astronomical data such as contained in files based on the FITS (Flexible Image Transport System) file format. It is written and is maintained by software engineers at the Subaru Telescope, National Astronomical Observatory of Japan.

The Ginga toolkit centers around an image display object which supports zooming and panning, color and intensity mapping, a choice of several automatic cut levels algorithms and canvases for plotting scalable geometric forms. In addition to this widget, a general purpose "reference" FITS viewer is provided, based on a plugin framework. A fairly complete set of standard plugins are provided for features that is expected from a modern FITS viewer: panning and zooming windows, star catalog access, cuts, star pick/fwhm, thumbnails, etc.

Pakken lmfit tilbyder en simpel, fleksibel grænseflade til ikkelineær optimering af kurvetilpasningsproblemer. Pakken udvider optimeringsfunktionerne i scipy.optimize ved at erstatte flydende kommatalsværdier for variablerne til optimering med parameterobjekterne. Disse parametre kan være faste eller varierende, have øvre og/eller lavere grænser placeret på deres værdi, eller skrevet som et algebraisk udtryk for andre parametre.

The principal advantage of using Parameters instead of simple variables is that the objective function does not have to be rewritten to reflect every change of what is varied in the fit, or what relationships or constraints are placed on the Parameters. This means a scientific programmer can write a general model that encapsulates the phenomenon to be optimized, and then allow user of that model to change what is varied and fixed, what range of values is acceptable for Parameters, and what constraints are placed on the model. The ease with which the model can be changed also allows one to easily test the significance of certain Parameters in a fitting model.

The lmfit package allows a choice of several optimization methods available from scipy.optimize. The default, and by far best tested optimization method used is the Levenberg-Marquardt algorithm from MINPACK-1 as implemented in scipy.optimize.leastsq. This method is by far the most tested and best support method in lmfit, and much of this document assumes this algorithm is used unless explicitly stated. An important point for many scientific analysis is that this is only method that automatically estimates uncertainties and correlations between fitted variables from the covariance matrix calculated during the fit.

A few other optimization routines are also supported, including Nelder-Mead simplex downhill, Powell's method, COBYLA, Sequential Least Squares methods as implemented in scipy.optimize.fmin, and several others from scipy.optimize. In their native form, some of these methods setting allow upper or lower bounds on parameter variables, or adding constraints on fitted variables. By using Parameter objects, lmfit allows bounds and constraints for all of these methods, and makes it easy to swap between methods without hanging the objective function or set of Parameters.

Finally, because the approach derived from MINPACK-1 usin the covariance matrix to determine uncertainties is sometimes questioned (and sometimes rightly so), lmfit supports methods to do a brute force search of the confidence intervals and correlations for sets of parameters.

Dette er Python 3-versionen af pakken.

PyDL consists of Python replacements for functions that are part of the IDL built-in library or part of astronomical IDL libraries. The emphasis is on reproducing results of the astronomical library functions. Only the bare minimum of IDL built-in functions are implemented to support this.

There are four astronomical libraries targeted:

• idlutils: a general suite of tools heavily used by SDSS.

• Goddard utilities: The IDL Astronomy User's Library, maintained by Wayne Landsman and distributed with idlutils.

• idlspec2d: tools for working with SDSS, BOSS and eBOSS spectroscopic data.

• photoop: tools for working with SDSS imaging data.

This is the Python 3 version of the package.

Pythonic wrapper around FFTW, the speedy FFT library. The ultimate aim is to present a unified interface for all the possible transforms that FFTW can perform.

Both the complex DFT and the real DFT are supported, as well as arbitrary axes of abitrary shaped and strided arrays, which makes it almost feature equivalent to standard and real FFT functions of numpy.fft (indeed, it supports the clongdouble dtype which numpy.fft does not).

pyFFTW is BSD-licensed and should not be confused with python-fftw, a GPL-licensed python module with the same aim of providing python bindings to FFTW3. Or python3-gpyfft, which provides bindings to the OpenCL FFT library clFFT.

This package provides the Python 3 bindings.

PyMOC tilbyder et Pythonkompatibelt bibliotek til at håndtere MOC'er.

Ofte er astronomiske undersøgelseskataloger eller billeder sparsomme og dækker kun en lille del af himlen. På et Multi-Order Coverage-kort er omfanget af data i et bestemt datasæt mellemlagret som et forudberegnet mask-billede. Den hierarkiske natur muliggør hurtige boolske operationer i billedrum uden at skulle udføre komplekse geometriske beregninger. Tjenester såsom VizieR tilbyder generelt MOC-masker, der giver en hurtigere oplevelse i grafiske applikationer såsom Aladin, eller for forskere, der hurtigt har brug for at finde ud af hvilke datasæt, der kan indeholde overlappende dækning.

Selve MOC-mask-billedet tesselleres og gemmes i NASA HealPix-format, kodet inde i en FITS-billedbeholder. Brug af HealPix-tessellationsmetoden (Hierarchical Equal Area isoLatitude Pixelization) sikrer, at mere præcision (billedpunkter) i masken er tilgængelig, når man beskriver komplekse former som tilnærmelsesvis undersøgelse eller polygonkanter, mens det kun behøver at gemme en enkelt stor celle/billedpunkt, når en dækning enten er helt indeni eller uden for masken. Kataloger kan gengives på masken som cirkler.

PyRAF is a command language for running IRAF tasks in a Python like environment. It works very similar to IRAF CL, but has been updated to allow such things as importing Python modules, GUI parameter editing and help. It can be imported into Python allowing you to run IRAF commands from within a larger script.

pysynphot simulates photometric data and spectra as they are observed with the Hubble Space Telescope (HST). Passbands for standard photometric systems are available, and users can incorporate their own filters, spectra, and data. pysynphot user interface allows you to:

• Construct complicated composite spectra from various grids of model atmosphere spectra, parameterized spectrum models, and atlases of stellar spectrophotometry.
• Simulate observations.
• Query the resulting structures for quantities of interest, such as countrate, effective wavelength, effective stimulus, as well as the wavelength and flux arrays.
• Plot HST sensitivity curves and calibration target spectra.
• Compute photometric calibration parameters for any HST instrument mode.

pysynphot can help HST observers to perform cross-instrument simulations, to examine the transmission curve of the HST Optical Telescope Assembly (OTA), and spectra of HST calibration targets. Expert users can take advantage of the control and data structures available in Python to easily perform repetitive operations such as simulate the observation of multiple type of sources through multiple observing modes.

Dette er en pakke til at omprojektere astronomiske billeder via diverse teknikker med en ensartet grænseflade. Omprojektering betyder omlægning af billeder fra et koordinatsystem til et andet (for eksempel ændringer af billedpunktsopløsning, retning, koordinatsystem). Implementeret i øjeblikket er omprojektering af himmelbilleder via interpolation, samt finde det præcise overlap mellem billedpunkter på himmelsfæren. Kan også omprojektere til/fra HEALPIX-projektioner.

Denne pakke indeholder Python 3-versionen af pakken.

SEP makes the core algorithms of Source Extractor available as a library of stand-alone functions and classes. These operate directly on in-memory arrays (no FITS files or configuration files). The code is derived from the Source Extractor code base (written in C) and aims to produce results compatible with Source Extractor whenever possible.

This Python module that wraps the C library in a Pythonic API. The Python wrapper operates on NumPy arrays.
