Description of the algorithms used by IPP full force stage

Inputs

During the skycalibration stage of stack photometry a new fiuts table is created which contains the parameters to be used for forced photometry.

This table has one row for each source with the following columns

Column	Value for Extended Source	Value for Extended Source
ID	IPP_IDET	IPP_IDET
X	X_PSF	X_EXT
Y	Y_PSF	Y_EXT
FLUX	PSF_INST_FLUX/EXPTIME	10**(-0.4*EXT_INST_MAG)
AP_RADIUS	AP_MAG_RADIUS	AP_MAG_RADIUS
KRON_RADIUS	MOMENTS_R1*2.5	MOMENTS_R1*2.5
PETRO_RADIUS	PETRO_RADIUS	PETRO_RADIUS
FIT_GALAXY	0	1
PSF_STAR	PM_SOURCE_MODE_PSFSTAR	PM_SOURCE_MODE_PSFSTAR
R_MAJOR	0	EXT_WIDTH_MAJ
R_MINOR	0	EXT_WIDTH_MIN
THETA	0	EXT_THETA
MODEL_TYPE	-1	model type for best fit
INDEX	0	0.5 / EXT_PAR_07
