kmos_std_star(7) Create the telluric correction frame.

SYNOPSIS

esorex kmos_std_star [OPTIONS] FILE.sof

DESCRIPTION

This recipe creates a telluric frame and a PSF frames.

Since there cannot be 1 std star per IFU in one exposure, we use several exposures in order to have at least one standard star and one sky in each IFU. The frames are organised following this logic: 1. For each IFU the first standard star in the list of frames is
   taken. All subsequent standard star exposures for this IFU are ignored 2. A closest in time sky exposure is uѕed 3. IFUs not containing a standard star and a sky will be empty in the result

NOISE_SPEC contains the shot noise [sqrt(counts*gain)/gain] If the exposures have been taken with KMOS_spec_cal_stdstarscipatt, an additional noise component is added: All existing sky exposures for an IFU are subtracted pairwise, spectra are extracted and the std deviation is computed
