measure_fwhm
- petrofit.modeling.measure_fwhm(image, plot=True, printout=True)[source]
Find the 2D FWHM of a background/continuum subtracted cutout image of a target. The target should be centered and cropped in the cutout. Use lcbg.utils.cutout for cropping targets. FWHM is estimated using the sigmas from a 2D gaussian fit of the target’s flux. The FWHM is returned as a tuple of the FWHM in the x and y directions.
- Parameters:
- imagearray like
Input background/continuum subtracted cutout image.
- printoutbool
Print out info.
- plotbool
To plot fit or not.
- Returns:
- tuplearray of floats
FWHM in x and y directions.
