Organisation

GILDAS consists of five major parts :

• The documentations, a set of PostScript files. An HTML documentation is also available.
• Dedicated utilities, which are programs using the SIC (Sympathetic Interpretor of Commands) user-friendly interface. Each utility normally has its own manual, accessible through the general documentation system.
  • GREG an all purpose 1-D and 2-D graphic program
  • CLASS (Continuum and Line Analysis Single-dish Software), for single-dish data processing.
  • ASTRO, an astronomical tool, very useful to prepare an observing session, or for amateur astronomy...
  • CLIC (Continuum and Line Interferometric Calibration), to calibrate interferometer data from Plateau de Bure.
  • Mapping, an interactive imaging and deconvolution package.
• Dedicated small programs to perform non interactive time consuming processing : smoothing, transpositions, fitting, etc... These programs will be called ``Tasks''. They are not intended for interactive use (although you may do it if you are an expert), but require instead a monitor program to activate them.
• Additional applications programs, such as FLUX or POINT to handle pointing and monitoring data for the IRAM PdB array.
