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.
