NAME

fors_subtract_sky_lss - Subtract sky from calibrated long slit exposure

SYNOPSIS

esorex fors_subtract_sky_lss [OPTIONS] FILE.sof

DESCRIPTION

This recipe is used to subtract the sky from wavelength calibrated scientific spectra pro‐ duced by the recipe fors_resample. A simple median signal level is subtracted from each image column. In the table below the MXU acronym can be read alternatively as MOS and LSS, depending on the instrument mode of the input data. The acronym SCI may be read STD in case of standard stars observations. Note that only LSS or LSS-like MOS/MXU data are to be processed by this recipe. Input files: DO category: Type: Explanation: Required: MAPPED_ALL_SCI_MXU Raw Scientific exposure Y Output files: DO category: Data type: Explanation: MAPPED_SCI_MXU FITS image Rectified scientific spectra MAPPED_SKY_SCI_MXU FITS image Rectified sky spectra

OPTIONS

Note that it is possible to create a configuration file containing these options, along with suitable default values. Please refer to the details provided by the 'esorex --help' command.
