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.
| Column | Description | |
|---|---|---|
| R | radius | pix |
| 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.
| Column | Description |
|---|---|
| GROWCURVEi | Empirical growth-curve for i-th aperture. |
| GROWCURVEERRi | Statistical error of GROWCURVE |
| RESGROWi | Residuals. |
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.
