XDIMSUM is a package for creating accurate sky subtracted images from sets of dithered observations. While the observations need not be in the infrared, the dominance of the variable sky background in infrared data requires dithering of many short exposures and recombination with careful sky subtraction to produce deep images. Hence the package is called "Experimental Deep Infrared Mosaicing Software" or XDIMSUM.

XDIMSUM is a variant of the DIMSUM package developed by P. Eisenhardt, M. Dickensen, S.A. Stanford, and J. Ward. F. Valdes (IRAF group) modified DIMSUM to support FITS format images, added the DIMSUM tutorial demos script, wrote the original version of this document, and repackaged DIMSUM for distribution as an IRAF external package. L. Davis (IRAF group) rewrote the the major DIMSUM scripts to improve their clarity, robustness, and efficiency, added new scripts for computing relative offsets, and documented the tasks. The new package uses the same default algorithms as DIMSUM but is sufficiently different in format that it has been renamed XDIMSUM.

SAOimage (pronounced S-A-0-image) is a utility for displaying astronomical images in the X11 window environment. It was written at the Smithsonian Astrophysical Observatory by Mike Van Hilst in 1990 and hass been maintained by Doug Mink. Image files can be read directly, or image data may be passed through a named pipe (Unix) or a mailbox (VMS) from IRAF display tasks. SAOimage provides a large selection of options for zooming, panning, scaling, coloring, pixel readback, display blinking, and region specification. User interactions are generally performed with the mouse. Mouse tracking in an image's world coordinate system, usually sky coordinates, was added in 1994. You can also plot catalogs over images with WCS information in their headers.

The SAOimage desktop includes, a main image display window, a button menu panel, a display magnifier, a pan and zoom reference image, and a color bar. A color table graph window can be brought up by clicking on the color bar.

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.

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.

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.
