Returns the standard deviation of pixel values of a CASA image.
See also
imageStds.
Usage:
au.imageStd(img, innerRadius=None, outerRadius=None, blc=None, trc=None, applymask=False)
Inputs:
- blc: integer tuple describing the bottom left corner of the region in which to compute the standard deviation
- trc: integer tuple describing the bottom left corner of the region in which to compute the standard deviation
- innerRadius: of square annulus in pixel units (not yet working)
- outerRadius: of square annulus in pixel units (not yet working)
- applymask: if True, then don't consider the values of masked pixels
Example:
CASA <14>: au.imageStd('Juno0.ms.cal.R1.image',blc=[375,550],trc=[625,650])
Out[14]: 0.00023071091507802376
