DESCRIPTION

This recipe does a complete science reduction. It runs all necessary calibration recipes depending on the availability of raw/processed calibration frames.

Input frames are all UVES-FIBER raw and reference frames: formatchecks, FIB_ARC_LAMP_FORM_RED, order definition frames, FIB_ORDER_FLAT_RED, biases, BIAS_RED, darks, DARK_RED, flats, SFLAT_RED, arc lamps, FIB_ARC_LAMP_RED, standard stars, FIB_STANDARD_RED a wavelength catalogue table,LINE_REFER_TABLE, and optionally a wavelength table of bright lines,LINE_INTMON_TABLE, used only for computing Quality Control parameters.

a reference standard star flux table, FLUX_STD_TABLE, a table describing the atmospheric extintion,EXTCOEFF_TABLE.

Optionally, science frames, SCIENCE_xxx, or UVES_SCI_POINT_xxx, or UVES_SCI_EXTND_xxx, or UVES_SCI_SLICER_xxx.

For further details on the data reduction and the input frame types refer to the man page of the individual recipes.

For low S/N, \'moffat\' or \'gauss\' are recommended (for robustness). For high S/N, \'virtual\' is recommended (for accuracy). In the case of virtual resampling, a precise determination of the order positions is required; therefore the order-definition is repeated using the (assumed non-low S/N) science frame (str; default: \'auto\').
