Documentation/Listing of tasks in analysisUtils (including some from analyzemscal and analyzemsimage)

The analysisUtils python package provides numerous (over 1300) analysis utilities written in python that are useful for ALMA (and in many cases VLA) data reduction. All the commands listed below exist in the current package, and there are links for pages that contain help and (sometimes) example usage. If the link is not found, it simply means that I have not created a help page yet. The commands are simply shown alphabetically, though they should really be sorted into categories at some point. Commands preceded by "amc." are inside analyzemscal.py, while commands preceded by "ami." are inside analyzemsimage.py, and commands preceeded by "vo." are inside visibilityOutliers.py. The rest are in analysisUtils.py. A subset of these commands is included in the help text at the CASA guide for analysis utilities (which contains a download link for the analysis_scripts tarball). The tarball is also available for download at Zenodo. As a quick mental reminder, a list of a superset of these commands can be obtained at any time from inside CASA (or python) by typing au.help(). Also, to find all functions containing a specified string in the name, use the au.help command. For, example: au.help('asdm'). The argument is case-insensitive. There is a companion python file that contains more generic, non-ALMA-specific code, called toddTools, which is not yet publicly available.
