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 88 of file pmObjects.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	SN
	approx signal-to-noise
int	nPixels
	Number of pixels used.
