imageImstats

Return to directory of Todd's CASA extensions

Runs imageImstat on a list of images and reports back a list of values of a keyword. See also imagePeak, imageSnr, imageStd, and imageCentroid to operate on images without using the casa imstat task.

Usage:

au.imageImstats(images, region='', keyword='flux', index=0, verbose=False)
Inputs:
  • img: name of CASA image
  • region: region to examine (default = whole image)
  • keyword: the dictionary key to extract and return
  • index: the index of the array to choose
  • verbose: if True, print the dictionary returned by imstat

Example:

CASA <11>: maxs = au.imageImstats('band6_9exec.commonMask.noobs*.image',region='both_arcs.crtf',keyword='max')
band6_9exec.commonMask.noobs0.image:  0.000140
band6_9exec.commonMask.noobs1.image:  0.000144
band6_9exec.commonMask.noobs2.image:  0.000138
band6_9exec.commonMask.noobs3.image:  0.000145
band6_9exec.commonMask.noobs4.image:  0.000137
band6_9exec.commonMask.noobs5.image:  0.000142
band6_9exec.commonMask.noobs6.image:  0.000137
band6_9exec.commonMask.noobs7.image:  0.000136
band6_9exec.commonMask.noobs8.image:  0.000139
