uves_cal_mbias - Creates the master bias frame
esorex uves_cal_mbias [OPTIONS] FILE.sof
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)
- --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.
