= psphot Galaxy Parameter Measurements =

For PV3 we plan to add some additional measurements of extended sources in psphotStack. This note describes these measurements
and includes some results from a test on the SAS2 region.

In a paper published in 2002 Simard et. al. [http://adsabs.harvard.edu/abs/2002ApJS..142....1S 2002 Simard et. al.] defined two measurements performed 
on the residual images for use in tghe morphological classification of galaxies.
