--- name: "sinfo_utl_skycor" section: "7" platform: "linux" package: "cpl-plugin-sinfo-doc" version: "2.5.2+dfsg-2" release: "Debian 8 (Jessie)" platforms: ["linux"] url: "https://new.carta.tech/sinfo_utl_skycor" --- # sinfo\_utl\_skycor(7) Sky lines residuals correction ## NAME sinfo\_utl\_skycor - Sky lines residuals correction ## 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** *\* 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** *\* 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** *\* 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** *\* 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** *\* 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** *\* 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** *\* 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** *\* 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** *\* 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** *\* 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** *\* 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** *\* 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** *\* 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** *\* 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** *\* 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.
