Aladin er et interaktivt himmelatlas, der giver brugeren mulighed for at visualisere digitale astronomiske billeder, at overlejre punkter fra astronomiske kataloger eller databaser og til interaktivt at tilgå relaterede data og information fra Simbaddatabasen, tjenesten VizieR og andre arkiver for alle kendte kilder i feltet.

Oprettet i 1999 af Centre de Données astronomiques de Strasbourg (CDS), og nu er Aladin et bredt anvendt værktøj for rammen Virtual Observatory (VO), som kan adressere udfordringer såsom at finde interessante data, tilgå og udforske distribuerede datasæt og visualisere data med flere bølgelængder. Overholder eksisterende VO-standarder eller kommende VO-standarder, forbindelse med andre visualiserings- eller analyseværktøjer, og mulighed for nemt at sammenligne heterogene data er de vigtigste områder, som gør, at Aladin er et funktionsrigt udforsknings- og integrationsværktøj.

Graftegninger håndterer problemet med at visualisere strukturel information ved at konstruere geometriske repræsentationer af abstrakte grafer og netværk. Automatisk oprettelse af graftegninger har en vigtig funktion i nøgleteknologier såsom databasedesign, programudvikling, VLSI og netværksdesign og i visuelle grænseflader i andre domæner. Situationer hvor disse værktøjer kan være specielt nyttige er:

• du ønsker at restrukturere et program og først skal du forstå relationerne mellem dets typer, procedurer og kildefiler
• du skal finde flaskehalse i en Internetmotor - ikke kun individuelle lænker, men deres relationer
• du fejlsøger en protokol eller mikroarkitektur repræsenteret som en endelig tilstandsmaskine og har brug for at regne ud hvordan en bestemt fejltilstand opstår
• du ønsker at gennemse et databaseskema, videndatabase eller distribueret program repræsenteret grafisk
• du ønsker at se et overblik over en samling af lænkede dokumenter
• du ønsker at se mønstre og interessefællesskaber i en database over telefonopkald eller e-post-beskeder

Denne pakke indeholder værktøjerne for kommandolinjen.

The drizzle library is a Python package for combining dithered images into a single image. This library is derived from code used in drizzlepac. Like drizzlepac, most of the code is implemented in the C language. The biggest change from drizzlepac is that this code passes an array that maps the input to output image into the C code, while the drizzlepac code computes the mapping by using a Python callback. Switching to using an array allowed the code to be greatly simplified.

STIL Tool Set er et sæt af kommandolinjeværktøjer baseret på STIL, Starlink Tables Infrastructure Library. Værktøjet håndterer behandlingen af tabulære data; pakken er blevet designet for, men er ikke begrænset til, astronomiske tabeller såsom objektkataloger. Nogle af værktøjerne er generiske og kan fungere med flere formater (inklusive FITS, VOTable, CDF, CSV, SQL og ASCII) og andre er specifikke for VOTable-formatet. På nogle måder udgør STILTS kommandolinjens modpart som den grafiske brugerflade for tabelanalyseværktøjet TOPCAT. Pakken er robust, fuldt dokumenteret og designet for effektivitet, specielt med meget store datasæt.

Denne pakke indeholder den kørbare fil.

Cloudy is an open source plasma simulation code that is designed to simulate conditions in a nonequilibrium gas, and predict its spectrum. The code incorporates physical processes from first principles, as much as possible. The goal is to simulate the ionization, level populations, molecular state, and thermal state, over all extremes of density and temperature. The approach of working from fundamental processes means that Cloudy can be applied to such diverse regions as the corona of a star, the intergalactic medium, or the accretion disk near the supermassive black hole in a luminous quasar.

MIRIAD is a radio interferometry data-reduction package, designed for taking raw visibility data through calibration to the image analysis stage. It has been designed to handle any interferometric array, with working examples for BIMA, CARMA, SMA, WSRT, and ATCA. A separate version for ATCA is available, which differs in a few minor ways from the CARMA version.

SPLAT is a graphical tool for displaying, comparing, modifying and analyzing astronomical spectra stored in NDF, FITS and TEXT files as well as in NDX format. It can read in many spectra at the same time and then display these as line plots. Display windows can show one or several spectra at the same time and can be interactively zoomed and scrolled, centered on specific wavelengths, provide continuous coordinate readout, produce printable hardcopy and be configured in many ways. Analysis facilities include the fitting of a polynomial to selected parts of a spectrum, the fitting of Gaussian, Lorentzian and Voigt profiles to emission and absorption lines and the filtering of spectra using average, median and line-shape window functions as well as wavelet denoising. SPLAT also supports a full range of coordinate systems for spectra, which allows coordinates to be displayed and aligned in many different coordinate systems (wavelength, frequency, energy, velocity) and transformed between these and different standards of rest (topocentric, heliocentric, dynamic and kinematic local standards of rest, etc). SPLAT is distributed as part of theStarlink(ascl:1110.012) software collection.

The cdsclient package is a set of C and shell routines which can be built on Unix stations or PCs running Linux, which once compiled allow to query some databases located at CDS or on mirrors over the network.

The cdsclient package includes two generic query programs:

• vizquery, a program to remotely query VizieR. It connects the VizieR server via the HTTP protocol (requires an access to the port 80)

• find_cats, a program for fast access to large surveys from a list of positions, via a dedicated client (requires an access to the port 1660) Specific programs like find2mass or finducac3 are connecting directly to one of the very large surveys available from CDS (a very large survey has 107 or more rows).

From a photometric catalogue, hyperz finds the redshift of each object by means of a standard SED fitting procedure, i.e. comparing the observed magnitudes with the expected ones, computed from template Spectral Energy Distributions. The set of templates used in the minimization procedure (age, metallicity, reddening, absorption in the Lyman forest, ...) is studied in detail, through both real and simulated data. The expected accuracy of photometric redshifts, as well as the fraction of catastrophic identifications and wrong detections, is given as a function of the redshift range, the set of filters considered, and the photometric accuracy. Special attention is paid to the results expected from real data.

PyDrizzle provides a semi-automated interface for computing the parameters necessary for runningDrizzle. PyDrizzle performs the task of determining the parameters necessary for aligning images based on the WCS information in the input image headers, as well as any supplemental alignment information provided in shift files, and combines the images onto the same WCS. Though it does not identify cosmic rays, it has the ability to ignore pixels flagged as bad, such as pixels identified by other programs as affected by cosmic rays.

GAIA is an image and data-cube display and analysis tool for astronomy. It provides the usual facilities of image display tools, plus more astronomically useful ones such as aperture and optimal photometry, contouring, source detection, surface photometry, arbitrary region analysis, celestial coordinate readout, calibration and modification, grid overlays, blink comparison, defect patching and the ability to query on-line catalogues and image servers. It can also display slices from data-cubes, extract and visualize spectra as well as perform full 3D rendering. GAIA uses the Starlink software environment (ascl:1110.012) and is derived from the ESO SkyCat tool(ascl:1109.019).

VirGO is the next generation Visual Browser for the ESO Science Archive Facility developed by the Virtual Observatory (VO) Systems Department. It is a plug-in for the popular open source software Stellarium adding capabilities for browsing professional astronomical data. VirGO gives astronomers the possibility to easily discover and select data from millions of observations in a new visual and intuitive way. Its main feature is to perform real-time access and graphical display of a large number of observations by showing instrumental footprints and image previews, and to allow their selection and filtering for subsequent download from the ESO SAF web interface. It also allows the loading of external FITS files or VOTables, the superimposition of Digitized Sky Survey (DSS) background images, and the visualization of the sky in a `real life' mode as seen from the main ESO sites. All data interfaces are based on Virtual Observatory standards which allow access to images and spectra from external data centers, and interaction with the ESO SAF web interface or any other VO applications supporting the PLASTIC messaging system.

VirGo is no longer supported by ESO. Last version was 1.4.5 from 2010.

VOSpec is a multi-wavelength spectral analysis tool with access to spectra, theoretical models and atomic and molecular line databases registered in the VO. The standard tools of VOSpec include line and continuum fitting, redshift and reddening correction, spectral arithmetic and convolution between spectra, equivalent width and flux calculations, and a best fitting algorithm for fitting selected SEDs to a TSAP service. VOSpec offers several display modes (tree vs table) and organising functionalities according to the available metadata for each service, including distance from the observation position.
