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

The analysisUtils python package provides numerous 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). 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.

Easy access in Charlottesville or Socorro

  • create a file in your home area: ~/.casa/init.py which contains:
import sys
sys.path.append("/users/thunter/AIV/science/analysis_scripts/")
import analysisUtils as au
  • start casa
  • Now you can access all functions, for example: au.plotbandpass()

Easy access for users outside of NRAO

  • download the tar file analysis_scripts.tar
  • unpack it in a designated area, such as your home directory -- it will make a subdirectory called analysis_scripts
  • edit your file ~/.casa/init.py to contain the following lines:
import sys
sys.path.append("/your_parent_directory/analysis_scripts/")
import analysisUtils as au
  • start casa
  • Now you can access all functions, for example: au.plotbandpass()
