NAME

       uves_cal_mbias - Creates the master bias frame

SYNOPSIS

       esorex uves_cal_mbias [OPTIONS] FILE.sof

DESCRIPTION

       This recipe creates a master bias frame by computing the median of all input bias frames. All input
       frames must have same tag and size and must be either BIAS_BLUE or BIAS_RED.

       On blue input the recipe computes one master bias frame; on red input a master bias frame for each chip
       is produced. The average, standard deviation and median of the master bias image(s) are written to the
       FITS header(s)

OPTIONS

       --debug <bool>
              Whether  or  not  to save intermediate results to local directory (bool; default: False). The full
              name of this option for the EsoRex configuration file is uves.debug [default = False].

       --plotter <str>
              Any plots produced by the recipe are redirected to the command specified by  this  parameter.  The
              plotting  command must contain the substring ´gnuplot´ and must be able to parse gnuplot syntax on
              its standard input. Valid examples of such a command may include ´gnuplot  -persist´  and  ´cat  >
              mygnuplot$$.gp´.  A finer control of the plotting options can be obtained by writing an executable
              script, e.g.  my_gnuplot.pl, that executes gnuplot after setting the desired gnuplot options (e.g.
              set terminal pslatex color). To turn off plotting, set  this  parameter  to  ´no´  (str;  default:
              ´no´).  The  full name of this option for the EsoRex configuration file is uves.plotter [default =
              no].

       --process_chip <str>
              For RED arm data process the redl, redu, or both chip(s) (str; default: ´both´). The full name  of
              this option for the EsoRex configuration file is uves.process_chip [default = both].

       --clean_traps <bool>
              Clean  detector  traps. If TRUE detector traps are interpolated.The bad pixels are replaced by the
              average of thenearest good pixels in the same column, or simply marked as bad.  The  positions  of
              bad  pixels  are  hard-coded  (as function of UVES chip). (bool; default: False). The full name of
              this option for the EsoRex configuration file is uves_cal_mbias.clean_traps [default = False].

       --stack_method <str>
              Method used to build master frame  (str; default: ´median´). The full name of this option for  the
              EsoRex configuration file is uves_cal_mbias.stack_method [default = median].

       --klow <float>
              Kappa  used to clip low level values, when method is set to ´mean´ (float; default: 5.0). The full
              name of this option for the EsoRex configuration file is uves_cal_mbias.klow [default = 5.0].

       --khigh <float>
              Kappa used to clip high level values, when method is set to ´mean´ (float; default: 5.0). The full
              name of this option for the EsoRex configuration file is uves_cal_mbias.khigh [default = 5.0].

       --niter <long>
              Number of kappa sigma iterations, when method is set to ´mean´  (long; default: 5). The full  name
              of this option for the EsoRex configuration file is uves_cal_mbias.niter [default = 5].

       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.
