Description

Calling Sequence

addpsf,image,x,y,f,psf

Inputs

image - 2-d array to insert the PSF(s) into (MODIFIED).
x - PSF x position (expected to be a float)
y - PSF y position (expected to be a float)
f - Scaling factor for source (multiplied against psf)
psf - Normalized PSF to use

Optional Input Parameters

Keyword Input Parameters

PSFMAX - 2-element vector that contains the x,y position of the
peak of the input PSF. These coordinates are in the
native image position coordinates of the PSF. If not
provided it will be computed. You can save on this
calculation by taking care of this outside this routine.

Outputs

image - modified version of the image with the PSFs added

2016/03/27, MWB, rewrite logic to eliminate possibility of bad array
indexing. If the requested location is not on the image
nothing is added.
