Autoflag Development

Goals

Current Status: Exploring the ALMA autoflag

1. Back in April, I finally got the heuristics script to produce the same output on Linux and Mac. (Shortly thereafter, I began having compile problems, and was then redirected to make listing tasks a higher priority.)
2. Today (2008Aug01), I am continuing with my heuristics investigation (primarily for the sake of learning Python, which I need to do for an NVO workshop I will attend in September). I am not getting the usual output from heuristics.
   • I did manage to compose a nice Python script based on the script Ed emailed me; this script resets the autoflag data and then runs autoflag again.

Accomplishments

• Ran ALMA autoflag in CASA using test data set. This is what I did:
  1. Stored source code in /users/jcrossle/NRAO/casa/autoflag
  2. Modified sfiReducer.py to work from directory autoflag. (This should be a one time thing.)
  3. Ran the following commands in casapy:

CASA <2>: sys.path.append('/users/jcrossle/NRAO/casa')

CASA <3>: import autoflag.sfiReducer

CASA <5>: r=autoflag.sfiReducer.SFIReducer('pdb_l02d_29-jan.raw')

CASA <6>: r.reduce(recipeName='antenna_recipe')

For this to work, the data must be in the same directory where I start casapy. (See email from John; 2008jan30.)

• Obtained ALMA pipeline autoflagging routine from John Lightfoot.
