deconvolveDiskFromBeam
Return to directory of Todd's CASA extensions
Deconvolve a disk from a Gaussian using a series of trial convolutions while
adjusting the guess accordingly. This is the inverse of the function
computeExpectedFWHM.
Usage:
au.deconvolveDiskFromBeam(fittedBeam, diskDiameter, tolerance=1e-05)
- fittedBeam: this is the geometric mean of the full size as fitted in the image
- diskDiameter: this is the expected diameter of the planet (or other disk-like object), in the same angular units as fittedBeam
- tolerance: the stopping criterion in units of the measured beam size
Example:
CASA <2>: au.deconvolveDiskFromBeam(30, 5)
Out[2]: 29.802554626902246
