Aladin is an interactive software sky atlas allowing the user to visualise digitised astronomical images, to superimpose entries from astronomical catalogues or databases, and to interactively access related data and information from the Simbad database, the VizieR service and other archives for all known sources in the field.

Created in 1999 by the Centre de Données astronomiques de Strasbourg (CDS), Aladin has become a widely-used tool of the Virtual Observatory (VO) framework capable of addressing challenges such as locating data of interest, accessing and exploring distributed datasets, and visualising multi-wavelength data. Compliance with existing or emerging VO standards, interconnection with other visualisation or analysis tools, and the ability to easily compare heterogeneous data are the key topics which allow Aladin to be a powerful data exploration and integration tool.

Fv provides a graphical user interface to data stored in FITS (Flexible Image Transport System) files. Local files can be created, viewed and edited, files on the internet can be opened read-only through the http and ftp protocols. Through the POWplot program, FITS data can be visualized in a large variety of styles. An interface to the SkyView online database allows for searching, downloading, and plotting of images and object lists for a region of the sky.

Graph drawing addresses the problem of visualizing structural information by constructing geometric representations of abstract graphs and networks. Automatic generation of graph drawings has important applications in key technologies such as database design, software engineering, VLSI and network design and visual interfaces in other domains. Situations where these tools might be particularly useful include:

• you would like to restructure a program and first need to understand the relationships between its types, procedures, and source files
• you need to find the bottlenecks in an Internet backbone - not only individual links, but their relationships
• you're debugging a protocol or microarchitecture represented as a finite state machine and need to figure out how a certain error state arises
• you would like to browse a database schema, knowledge base, or distributed program represented graphically
• you would like to see an overview of a collection of linked documents
• you would like to discover patterns and communities of interest in a database of telephone calls or e-mail messages

This package contains the command-line tools.

The MSCRED external package is used to reduce CCD mosaic data in multiextension FITS format. This format is produced for example by the Data Capture Agent when observing with the NOAO CCD Mosaic Imager, as well as similar instruments from AAO, CFA, CFHT, ESO, INT and others.

The tasks in the mscred package perform the following functions:

• display the mosaic data as an apparent single mosaic image,
• provide interactive examination of displayed mosaic data,
• combine multiple calibration exposures into master calibration files,
• perform the basic CCD calibrations such as zero level and gain,
• reconstruct a single mosaic image with distortions removed,
• register and combine dithered operations, and
• save and restore data on tape.

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.

The STIL Tool Set is a set of command-line tools based on STIL, the Starlink Tables Infrastructure Library. It deals with the processing of tabular data; the package has been designed for, but is not restricted to, astronomical tables such as object catalogues. Some of the tools are generic and can work with multiple formats (including FITS, VOTable, CDF, CSV, SQL and ASCII), and others are specific to the VOTable format. In some ways, STILTS forms the command-line counterpart of the GUI table analysis tool TOPCAT. The package is robust, fully documented, and designed for efficiency, especially with very large datasets.

TOPCAT is an interactive graphical viewer and editor for tabular data. Its aim is to provide most of the facilities that astronomers need for analysis and manipulation of source catalogues and other tables, though it can be used for non-astronomical data as well. It understands a number of different astronomically important formats (including FITS and VOTable) and more formats can be added.

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.

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.

PyMidas is an interface between Python and MIDAS, the major ESO legacy general purpose data processing system. PyMidas allows a user to exploit both the rich legacy of MIDAS software and the power of Python scripting in a unified interactive environment. PyMidas also allows the usage of other Python-based astronomical analysis systems such asPyRAF.

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.
