Construct a _PsfShapeHistogram
The maximum seeing FWHM that can be tolerated is [xy]Max/2.35 pixels.
The 'resolution' of stars vs galaxies/CRs is provided by [xy]Size/[xy]Max.
A larger (better) resolution may thresh the peaks, but a smaller (worse)
resolution will allow stars and galaxies/CRs to mix. The disadvantages of
a larger (better) resolution can be compensated (some) by using multiple
histogram peaks.
@input[in] [xy]Size: the size of the psfImage (in pixels)
@input[in] ixxMax, iyyMax: the maximum values for I[xy][xy]
