Not all angles are always present. | |||||||||||||||||||||||||||
| ALGORITHM |
Description of algorithms: num_slit: number of slitlets identified n_lin_av: number of identified arc lines per CCD row, averaged over all slitlets disp: mean dispersion, averaged over all slitlets | |||||||||||||||||||||||||||
| CERTIF |
Reasons for rejection: - unusual shape of non-linear terms (e.g. double peak/valley); - curved/slanted lines in the reduced arc image; - missing/empty slitlets in normalized flat field image; - spatially curved slitlets in the normalized master flat or rebinned arc frame - different line widths are NO cause for rejection, as observers may use different slit widths in one setup | |||||||||||||||||||||||||||
| COMMENTS | Gaps due to unused slitlets do not show up in the reduced arc frame, which shows only detected slitlets. | |||||||||||||||||||||||||||
