AIPS Astronomical Image Processing System: a software package for calibration, data analysis, image display, plotting, and a variety of ancillary tasks on Astronomical Data. It comes from the National Radio Astronomy Observatory. AIPS++ Astronomical Information Processing System: a very powerful package for astronomical data reduction, written in C++ and Glish (a C-like interpreter). AVSOMAT AVSOMAT is designed to increase the productivity of obtaining, reducing and reporting large numbers of CCD images of variable stars. It consists of a binary tool for reducing images and a collection of CommonLisp functions for dealing with collections of images, information about stars, former observations, etc. CHIANTI CHIANTI consists of a critically evaluated set of up-to-date atomic data, together with user-friendly programs written in Interactive Data Language (IDL), to analyse the spectra from astrophysical plasmas. CMBFAST CMBFAST is a code for calculating the linear cosmic microwave background (CMB) anisotropy spectra based on integration over the sources along the photon past light cone. In this approach the temperature anisotropy is written as a time integral over the product of a geometrical term and a source term. Cora Cora is a tool to obtain the number of counts in emission lines. It is a C-written program with graphical user interface The program can also be run in IDL. Draco The use of large format detectors, increased access to very large astronomical databases, and other developments in observational astronomy have led to the situation where many astronomers are overwhelmed by the reduction and analysis process. Draco is a novel approach to data reduction and analysis which works in conjunction with existing analysis systems such as STSDAS/IRAF, IDL, etc. Funtools Funtools, is a "minimal buy-in" FITS library and utility package from the SAO/HEAD R&D group. The Funtools library provides simplified access to FITS images and binary tables, as well as to raw array and binary event lists. The Funtools utilities provide high-level support for processing astronomical data. Photom These programs are designed to take raw, instrumental measurements of stellar brightness and convert them to calibrated magnitudes on some standard system. PROS ROS is a multi-mission x-ray analysis software system designed to run under the Image Reduction and Analysis Facility (IRAF). The analysis of x-ray data differs from that of other wavelengths due to the nature of x-ray data. The scarcity of data, the low signal-to-noise ratio and the large gaps in exposure time make data screening and masking an important part of the analysis process. SExtractor SExtractor is a program that builds a catalogue of objects from an astronomical image. Although it is particularly oriented towards reduction of large scale galaxy-survey data, it performs rather well on moderately crowded star fields.
