Analysis Utilities (or analysisUtils for short) is a small set of Python source code files that provide a number of analysis and plotting utilities. The utilities were developed for ALMA data reduction and are, in many cases, also useful for EVLA data reduction.
First, download Analysis Utilities from LINKHERE and extract the tar ball. From a Unix command line this can be done with
$ tar xvf analysis_scripts.tar
Edit your casapy init file in $HOME/.casa/init.py, and add the following
import sys sys.path.append("/PATH_TO_ANALYSIS_SCRIPTS") import analysisUtils as au
where /PATH_TO_ANALYSIS_SCRIPTS is the path to the directory you just extracted from the tar ball. When this is done, start casapy and you will have access to all Analysis Utilities functions described below.
