Appendix A: Structure of AIPS++

To simplify use of AIPS++, the available functionality is split into a hierachy of packages and modules. One can choose to use just those packages and modules which are of direct interest. Each module holds a number of toolsand global functions.

packages

The top layer of the AIPS++ software system contains packages. Each package contains specific modules. Some examples of packages are:

synthesis: : for processing aperture synthesis data with modules for calibrating, editing, visibility plotting, imaging, and deconvolving.
general: : contains modules of general utility such as units and measures, coordinate conversions, image analysis, and manipulations.
utility: : for printing, catalog handling, and mathematical operations.
display: : for plotting, and displaying.
dish: : for processing single-dish data.
atnf: : contains modules relevant for data from the Australia Telescope.
nrao: : contains modules relevant for data from NRAO telescopes, currently the GBT and the VLA.

modules

Each package contains a specific set of modules. modules are a group of closely related applications. For example, the modules of package Synthesis are:

calibrater: calibrating UV data
componentmodels: making source component models
imager: imaging and deconvolution, wide-field imaging, mosaicing, etc..
simulator: simulating UV and other data
msplot: plotting visibility data in various ways
