The default output device is `ASCII', i.e. stdout:
# Focus Intens SigX SigY <Sig> d<Sig> 1 750.0 2.39e+10 1.242 1.574 2.005 0.041 2 800.0 2.53e+10 1.205 1.506 1.928 0.039 3 850.0 2.66e+10 1.174 1.459 1.872 0.038 ...
DISLINones: CONS (X-window), EPS, PDF, PNG, etc. (see complete list at http://www.linmpi.mpg.de/dislin/kap6.html#METAFL)
The value used for the best-focus determination is <Sig> (RMS of SigX and SigY). It appears that the focus position is not very dependant on the quantity used (e.g. intensity)
-quietstandard option for minimal output.
Test different zones in the arc frame (size and position, but beware of 0th and 2nd orders)
Fit multiple zones in the arc frame and derive a CCD-tilt
Check out why the Y-error bars are so different between the red and blue channels. The formal error estimates derived with
nllsqfit_bnd seem theoritically correct.
