Detailed Description

pmMoments data structure

One of the simplest measurements which can be made quickly for an object are the object moments. We specify a structure to carry the moment information for a specific source:

Definition at line 24 of file pmMoments.h.

Data Fields
float	x
	X-coord of centroid.
float	y
	Y-coord of centroid.
float	Sx
	x-second moment.
float	Sy
	y-second moment.
float	Sxy
	xy cross moment.
float	Sum
	Pixel sum above sky (background).
float	Peak
	Peak counts above sky.
float	Sky
	Sky level (background).
float	dSky
	local Sky variance
float	SN
	approx signal-to-noise
int	nPixels
	Number of pixels used.
