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 Input files: DO KMOS category Type Explanation Required #Frames -------- ----- ----------- -------- ------- STD RAW Std. star & sky exposures Y >=1 XCAL F2D x calibration frame Y 1 YCAL F2D y calibration frame Y 1 LCAL F2D Wavelength calib. frame Y 1 MASTER_FLAT F2D Master flat frame Y 1 WAVE_BAND F2L Table with start-/end-wl Y 1 ILLUM_CORR F2I Illumination correction N 0,1 SOLAR_SPEC F1S Solar spectrum N 0,1 (only for G stars) ATMOS_MODEL F1S Model atmospheric transmisson N 0,1 (only for OBAF stars in K band) SPEC_TYPE_LOOKUP F2L LUT eff. stellar temperature N 0,1 Output files: DO KMOS category Type Explanation -------- ----- ----------- TELLURIC F1I The normalised telluric spectrum (including errors) STAR_SPEC F1I The extracted star spectrum (including errors) STD_IMAGE F2I The standard star PSF images STD_MASK F2I The mask used to extract the star spec NOISE_SPEC F1I The extracted noise spectrum
