The optional parameter --verbose to gphot invokes addiding of GROWFUNC and GROWDATA extension to all files together with plotting results to a graphical PNG file.
|GROWCURVE||growth curve value at R|
|RADIALPROFILE||Radial profile at R|
GROWFUNC tabulates growth-curve at more sampled radiuses than extension GROWCURVE contains. The curve is interpolated by smoothing cubic spline from the derived curve.
|GROWCURVEi||Empirical growth-curve for i-th aperture.|
|GROWCURVEERRi||Statistical error of GROWCURVE|
GROWDATA extension stores empirical growth-curves of stars on image. Growth curves of all stars are plotted in light blue, ones used for growth-curve construction in dark blue. Residuals between final curve and the data are plotted by RESGROW column. Order number in GROWDATA refers to GROWPHOT extension.
