     1== P3.17        Instrumental throughput and absolute flux calibration ==
    22•       **Phase**               :       3 
    33•       **Status**              :       Draft   
    44•       **Category**            :       Nighttime testing (functionality and operability) (C4)
    5 •       **Recurrence**  :       once at commissioning and then for each LSS observation observations.
    6 •       **Duration**            :       20 minutes
     5•       **Recurrence**  :       once every month starting from commissioning and then on                                request for accurate photometry (using CI and DBI).
     6•       **Duration**            :       1 hour (per configuration, also depends on mag of star)
    77**Description**
    8 •       Atmospheric calibration to remove telluric atmospheric features from the stellar spectrum and get absolute flux calibration per spectral resolution element.
     8•       Throughput calibration to obtain absolute flux calibration of science targets.
    99**Prerequisites**
    1010•       Authorize SHARK-NIR on the SX side.
    1111•       Atmospheric conditions: AO working conditions.
    12 •       Bad pixel map, Background or Dark, Flat-field, wavelength calibration.
     12•       Bad pixel map, Background or Dark, Flat-field, distortion map
    1313**Procedure**
    14 •       Observe the spectrum of a featureless (and/or standard) star at similar airmass that of the science target.
     14•       Observe a spectro-photometric standard star of known magnitude with no coronagraph and for required filters.
    1515**Success criteria**
    16 •       Better than 10% for absolute flux calibration and for average residuals from telluric removal.
     16•       Flux measurement better than 10%
    1717**Notes**
    18 •       Same as activity 7.4 in AD4
     18•       Same as activity 7.3 in AD4
    1919**LBTO support**
    20 •       Support from LBTI/LBTO?
     20•       SOUL-AO support
