List Flag Statistics for each "Reason"

Flag_reason_stats.py‎ is a script that can list the statistics of flags in categories of "reason".

Here is an example, on a small MS where spw=8 is filled with exact zeros, spw='9' has RFI, and I want to clip zeros and run tfcrop, and count zeros and RFI separately.

execfile('flag_reason_stats.py');

CASA <17>: countlist = task_reason_stats(msname='Four_ants_3C286.ms',spw='8,9');
Summary  0 ( Zeros ) :  Flagged :  274944.0  out of  549888.0
Summary  1 ( TFCrop ) :  Flagged :  18633.0  out of  549888.0

CASA <18>: countlist = task_reason_stats(msname='Four_ants_3C286.ms',spw='9');
Summary  0 ( Zeros ) :  Flagged :  0.0  out of  274944.0
Summary  1 ( TFCrop ) :  Flagged :  18633.0  out of  274944.0

CASA <19>: countlist = task_reason_stats(msname='Four_ants_3C286.ms',spw='8');
Summary  0 ( Zeros ) :  Flagged :  274944.0  out of  274944.0
Summary  1 ( TFCrop ) :  Flagged :  0.0  out of  274944.0
