uvfstats and large datasets
Just wondering - are there any known problems with 'uvfstats' handling large datasets? I tried to use it on a uv data file for a large mosaic, and it's spitting out negative numbers for the flagged percentage like -8% and other strange things. I know for a fact that the flagged percentage is more like 30%. Using the line parameter to reduce the bandwidth to 128MHz and below doesn't seem to improve the situation much either...

Hi,
you're correct, it doesn't handle large datasets well, in percentage mode it gives negative numbers and in absolute mode the numbers overflow the space.
If you specify mode=channel it does work, but gives way to much output for CABB data.
I'll have a look at it and let you know when it's fixed.
Cheers,
Mark
