Growth-Curve Photometry

Growth-curve photometry is primary intended for the absolute photometry calibration. This routine constructs a mean radial growth-curve by using of machine selected bright stars. Total absolute fluxes of all stars are determined from the growth-curve. As a side effect, the method produces less scattered data for well radially defined images of stars.

Description

Growth-curve photometry determines absolute fluxes of all star-like objects of frames. sum of counts from a star in predefined apertures.

With this (common) parameter, additional extensions GROWFUNC and GROWDATA are added to processed files and create a report file (replaces .fits with .png) with plotted details about growth curve photometry. See detailed description. The graphs requires gnuplot to be installed. Any error is silently ignored.

Examples

Common usage
