Here is one additional runstring that caused this error:
apero_ccf_nirps_he.py 2024-08-08 NIRPS_2024-08-09T07_47_45_862_pp_e2dsff_tcorr_A.fits --rv=nan --width=300.0 --step=0.25 --masknormmode=order --database=True --plot=0 --program=CCF[01253] --recipe_kind=rv-tcorr --parallel=True --shortname=CCF --crunfile=online_run.ini
This seems to be a problem that the guess used for the CCF is not good (and the data is pretty bad too) probably unable to fit a gaussian to the data.
Need to have a good metric on whether we can measure a gaussian, or have a better guess (that doesn't go out-of-bounds) or catch more exceptions and skip these orders that fail.
This was due to the curve_fit
sigma=sig
term having nans in (we test the CCF for nans but didn't test the sig term) the curve_fit
error really doesn't help here!
