MIRIAD task for getting integrated flux of region

Postby and460 » Mon Aug 19, 2013 3:29 pm

Hi all,

Just wanting to know if there is such thing as a task that will give you the integrated flux of a region in units of Jy/beam, sort of like the 's' key will in kvis? IMSTAT seems to give the max, min, std, mean and sum of a defined region, but the number returned for 'sum' doesn't seem to have the beam area divided out. I suppose I could do it manually, but I was wondering if there was a task that would take care of it for me.

Cheers,

Craig.

Hi Craig,

imstat has a 'tb' option that calculates total flux in Kelvin which is probably not what you're after.
The task histo lists the min,max,mean, rms and total flux in the region specified, the latter divided by the beam area if the map units are Jy/beam.

Cheers,

Mark
