fors_remove_bias - Subtract bias from input frame
esorex fors_remove_bias [OPTIONS] FILE.sof
This recipe is used to subtract the overscan and master bias(produced by the recipe fors_bias) from one raw data frame. The overscan regions, if present, are used to compensate for variations of the overall bias level between master bias and input raw frame. The overscan regions are then trimmed from the result. The recipe should allow any fors frame. Input files: DO category: Type: Explanation: Required: ANY_CAT Raw Raw data frame Y MASTER_BIAS Calib Master bias frame Y Output files: DO category: Data type: Explanation: ANY_CAT_UNBIAS FITS image Bias subtracted frame
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.
The full documentation for the fors pipeline can be downloaded as a PDF file using the following URL: ftp://ftp.eso.org/pub/dfs/pipelines/fors/fors-pipeline-manual-4.9.pdf An overview over the existing ESO pipelines can be found on the web page http://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 http://packages.python.org/python-cpl/index.html for further information.
