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
--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].
--dc_mask_x <int>
x-size (pixel) of the mask starting at (x,y) = (1,1) (int; default: 1). The full name of this
option for the EsoRex configuration file is uves_cal_mbias.dc_mask_x [default = 1].
--dc_mask_y <int>
y-size (pixel) of the mask starting at (x,y) = (1,1) (int; default: 1). The full name of this
option for the EsoRex configuration file is uves_cal_mbias.dc_mask_y [default = 1].
--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].
--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].
--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].
--niter <int>
Number of kappa sigma iterations, when method is set to ´mean´ (int; default: 5). The full name
of this option for the EsoRex configuration file is uves_cal_mbias.niter [default = 5].
--pd_compute <bool>
Determine Fixed Pattern Noise. If TRUE the Fixed Patter Noise power spectrum is determined.(as
function of UVES chip). (bool; default: False). The full name of this option for the EsoRex
configuration file is uves_cal_mbias.pd_compute [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].
--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].
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.
