NAME¶fors_flatfield - Flat field correction of input frame
SYNOPSIS¶esorex fors_flatfield [OPTIONS] FILE.sof
DESCRIPTION¶This recipe is used to divide the input frame by the normalised flat field frame produced by recipe fors_normalise_flat. The input frame must be already bias subtracted (e.g., by recipe fors_remove_bias).
In the table below the MXU acronym can be alternatively read as MOS and LSS.
DO category: Type: Explanation: Required: SCIENCE_UNBIAS_MXU or STANDARD_UNBIAS_MXU Raw Bias subtracted frame Y MASTER_NORM_FLAT_MXU Calib Normalised flat frame Y
DO category: Data type: Explanation: SCIENCE_UNFLAT_MXU or STANDARD_UNFLAT_MXU FITS image Flat field corrected frame
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.

An overview over the existing ESO pipelines can be found on the web page https://www.eso.org/sci/software/pipelines/.
Basic documentation about the EsoRex program can be found at the esorex (1) man page.
It is possible to call the pipelines from python using the python-cpl package. See https://packages.python.org/python-cpl/index.html for further information.
