This chapter provides a list of common AIPS tasks, and their equivalent AIPS++ tool or tool function names. The two packages differ in both their architecture and calibration and imaging models, and there is often not a direct correspondence. However, this index does provide a scientific user of AIPS++ who is familiar with AIPS, with a simple translation table to map their existing data reduction knowledge to the new package.
The index includes common AIPS tasks and verbs; adverbs are not included. Capabilities which exceed those available in AIPS are not listed here by definition; users are referred to the other chapters in this guide for full descriptions of these capabilities. However, the current index entries offer starting points in which to explore related facilities in AIPS++ which exceed those in AIPS.
AIPS++is structured as a toolkit at the lower levels, while AIPS is a comprehensive collection of more monolithic applications. In general, the counterpart of an AIPS task is an AIPS++tool function, although the toolkit structure of AIPS++will generally mean that these functions are more fine-grained, except for the more integrated tools at the higher levels (such as map. The counterparts of AIPS adverbs are the parameters of AIPS++tool functions. The command-line interpreter in AIPS is POPS, while the counterpart in AIPS++is Glish. Scripts in Glish are more powerful equivalents of AIPS runfiles.
