.TH SINFO_UTL_SKYCOR "7" "3.1.0" "sinfo_utl_skycor" "sinfo recipes" .SH NAME sinfo_utl_skycor \- Sky lines residuals correction .SH SYNOPSIS esorex .B sinfo_utl_skycor [OPTIONS] FILE.sof .SH DESCRIPTION This recipe perform a correction of possible sky line residuals in the object cube after standard data reduction. .PP Input frames are cubes with target and sky observations. .PP Their tags can be respectively OBS_OBJ (or OBS_PSF or OBS_STD) and OBS_SKY. .PP The output is a cube with same tag as the corresponding input target frame. .PP .SH OPTIONS .TP \fB\-\-skycor\-mask_ws\fR \fI\fR Starting wavelength for object\-sky cross correlation (float; default: 1.4).
