NAME
kmos_std_star - 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
