The structure of the IMAGER program

The IMAGER program supports

• The manipulation (e.g. resampling), visualization and flagging of uv tables;
• The imaging of uv tables in dirty maps and beams;
• The deconvolution of dirty maps;
• The inclusion of short-spacings;
• The visualization and analysis of spectral cubes;
• The self-calibration.
• A simulator for observations with ALMA or NOEMA (and other arrays).

It consists in a collection of commands, either dedicated to image display (the DISPLAY\ language), UV handling and imaging with deconvolution (the CLEAN\ language), implementing basic functionalities (the SIC\, GREG\, or CALIBRATE\ families of languages), advanced methods and image analysis tools ( ADVANCED\ language) or even complex suites of operations (the BUNDLES\ language). A complete pipeline is available through the IMAGER\ language.

A few additional widgets are grouped in the IMAGER main menu to provide more integrated interfaces to the above possibilities, or more elaborate control. While these widgets may still evolve to offer more flexibility, the commands are in general very stable, though minor syntax adjustments may occur (usually to implement a more convenient syntax, but keeping as much as possible backward compatibility as a major constraint).
