PyEphem provides an ephem Python package for performing high-precision astronomy computations. The underlying numeric routines are coded in C and are the same ones that drive the popular XEphem astronomy application, whose author, Elwood Charles Downey, generously gave permission for their use in PyEphem.

The name ephem is short for the word ephemeris, which is the traditional term for a table giving the position of a planet, asteroid, or comet for a series of dates.

This package contains the Python 2 version of the package.

Gyoto aims at providing a framework for computing orbits and ray-traced images in General relativity.

This package also includes a Gyoto plug-in allowing to write new Gyoto objects in the Python 2 language.

This package provides an extension for the Python 2 programming language exposing the Gyoto facilities. It allows using Gyoto interactively from the Python prompt or running complex Gyoto scripts.

The lmfit Python package provides a simple, flexible interface to non-linear optimization or curve fitting problems. The package extends the optimization capabilities of scipy.optimize by replacing floating pointing values for the variables to be optimized with Parameter objects. These Parameters can be fixed or varied, have upper and/or lower bounds placed on its value, or written as an algebraic expression of other Parameters.

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.

This is the Python 2 version of the package.

Numpy enthält ein mächtiges N-dimensionales Array-Objekt, hochentwickelte (Sende)-Funktionen, Werkzeuge zur Integration von C-/C++- und Fortran-Code sowie nützliche Fähigkeiten für Lineare Algebra, Fourier-Transformation und Zufallszahlen.

Numpy ersetzt die Module python-numeric und python-numarray, die jetzt abgelehnt sind und nicht mehr genutzt werden sollten, außer um ältere Software zu unterstützen.

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 python-gpyfft, which provides bindings to the OpenCL FFT library clFFT.

This package provides the Python 2 bindings.

The VOTable format is defined by the International Virtual Observatory Alliance to facilitate data exchange in astronomy. This library implements most of the specification and offers simple and advanced, streaming interfaces. Also included is a simple client to query TAP servers.

There are many other libraries to parse VOTables into python programs, the default probably being astropy's. This one is geared for maximal control, streaming, and the possibility to write fairly mad instance documents.

Sherpa is a Python package for modeling and fitting. It enables the user to construct complex models from simple definitions and fit those models to data, using a variety of statistics and optimization methods.

It was originally developed by the Smithsonian Astrophysical Observatory / Chandra X-Ray Center as part of the larger CIAO package for X-ray data analysis
