SYNOPSIS

esorex sinfo_utl_skycor [OPTIONS] FILE.sof

DESCRIPTION

This recipe perform a correction of possible sky line residuals in the object cube after standard data reduction.

Input frames are cubes with target and sky observations.

Their tags can be respectively OBS_OBJ (or OBS_PSF or OBS_STD) and OBS_SKY.

The output is a cube with same tag as the corresponding input target frame.

OPTIONS

--skycor-mask_ws <float>

Starting wavelength for object-sky cross correlation (float; default: 1.4). The full name of this option for the EsoRex configuration file is sinfoni.sinfo_utl_skycor.mask_ws [default = 1.4].

--skycor-mask_we <float>

End wavelength for object-sky cross correlation (float; default: 2.5). The full name of this option for the EsoRex configuration file is sinfoni.sinfo_utl_skycor.mask_we [default = 2.5].

--skycor-min_frac <float>

Threshold value for fraction of spatial pixels to be sky (float; default: 0.8). The full name of this option for the EsoRex configuration file is sinfoni.sinfo_utl_skycor.min_frac [default = 0.8].

--skycor-sky_bkg_filter_width <long>

Width of sky-thermal background pre filter (to remove emission lines before fitting a Black Body). (long; default: 12). The full name of this option for the EsoRex configuration file is sinfoni.sinfo_utl_skycor.sky_bkg_filter_width [default = 12].

--skycor-line_hw <float>

Threshold value for full width in pixels of unresolved emission line. Lines with FWHM smaller than this value are not considered in the object-sky cross correlation and in computation of the optimal sky lines scaling factor (float; default: 4.0). The full name of this option for the EsoRex configuration file is sinfoni.sinfo_utl_skycor.line_half_width [default = 4.0].

--skycor-scale_method <long>

Optimal sky lines scaling factor computation method: amoeba fit (0), maximum likelihood (1) (long; default: 1). The full name of this option for the EsoRex configuration file is sinfoni.sinfo_utl_skycor.scale_method [default = 1].

--skycor-rot_cor <bool>

Computes scaling factor correction due to rotational levels transitions (bool; default: False). The full name of this option for the EsoRex configuration file is sinfoni.sinfo_utl_skycor.rot_cor [default = False].

--skycor-fit_obj_noise <bool>

Do Gaussian fit of object noise (bool; default: False). The full name of this option for the EsoRex configuration file is sinfoni.sinfo_utl_skycor.fit_obj_noise [default = False].

--skycor-niter <long>

Number of iterations of background fit (long; default: 10). The full name of this option for the EsoRex configuration file is sinfoni.sinfo_utl_skycor.niter [default = 10].

--skycor-pshift <float>

Sky spectrum shift towar object (float; default: 0.0). The full name of this option for the EsoRex configuration file is sinfoni.sinfo_utl_skycor.pshift [default = 0.0].

--skycor-llx <long>

Lower left X defining object spectrum location (long; default: 1). The full name of this option for the EsoRex configuration file is sinfoni.sinfo_utl_skycor.llx [default = 1].

--skycor-lly <long>

Lower left Y defining object spectrum location (long; default: 1). The full name of this option for the EsoRex configuration file is sinfoni.sinfo_utl_skycor.lly [default = 1].

--skycor-urx <long>

Upper right X defining object spectrum location (long; default: 64). The full name of this option for the EsoRex configuration file is sinfoni.sinfo_utl_skycor.urx [default = 64].

--skycor-ury <long>

Upper right Y defining object spectrum location (long; default: 64). The full name of this option for the EsoRex configuration file is sinfoni.sinfo_utl_skycor.ury [default = 64].

--skycor-sub_thr_bkg_from_obj <bool>

Subtract thermal background contribute from object spectra. Set it to TRUE if stack-sub_raw_sky is set to FALSE (bool; default: False). The full name of this option for the EsoRex configuration file is sinfoni.sinfo_utl_skycor.sub_thr_bkg_from_obj [default = False].

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.
