FIT/ROMAFOT

FIT/ROMAFOT frame [int_tab] [thres,sky] [sig,sat,tol,iter] [meth[,beta]]
[fit_opt] [mean_opt]

Since the user is now at the same point discussed in the interactive procedure, detailed information is not needed here.

The logfile will contain the results of the fit. If the command has found difficulties for more than a few percent of the objects, something is wrong (e.g. wrong PSF parameters). If the statistics are acceptable the user may wish to display some windows with ANALYSE/ROMAFOT (see above). Normally in this phase, in order to realise and to correct the ``bad'' windows (NO CONVERGENCY or ``more than ... iterations'') one should look at them. This is easily accomplished with ANALYSE/ROMAFOT using the commands ``4'', ``S'', ``O''. These commands will give the windows which did not find appropriate convergence on all the stars, or ``4'', ``S'', ``I'' to give windows which needed more than n iterations.

The user can intervene as described in the interactive procedure. If needed, fits can be repeated for these windows to have the situation where all windows have been reconstructed as a sum of a number of elementary components. To check the quality of such reconstruction, a further crossing-over from the automatic path to the interactive path may be done. In fact, ANALYSE/ROMAFOT allows the interactive check of all the windows. To perform the automatic check one can execute the command EXAMINE/ROMAFOT.
