| ALGORITHM |
The recipe performs a cross-correlation between a catalog and the input frame and
determines polynomial coefficients. It also calls a physical model that provides a wavelength map. lambda_cent: central wavelength on each detector according to cross-correlation solution dispersion: dispersion (nm/pix) from cross-correlation solution xcorr: cross-correlation value; between 0.2 and 1.0 for a successful correlation; -1 means failure lamp_eff: sum of pixel values in a small area around one fibre, backgound subtracted resolution: spectral resolving power resol_fwhm: average FWHM of arc lines in pixels temp_grat: grating temperature num_overexp: number of pixels with values above level_overexp | |||||||||||||||||||||||||||
| CERTIF |
Reasons for rejection: low cross-correlation (or failure) for a setting that can normally be well calibrated; for most standard settings, scoring is available on cross-correlation; there are also reference frames available for comparison | |||||||||||||||||||||||||||
