    79**Description**
    8 •       Determine distortion map of science frame. Monitor distortion coefficient with time (weekly calibration) and measure the precise distortion of a given observation in any setup, if requested.
     10- Atmospheric calibration to remove telluric atmospheric features from the stellar spectrum and get absolute flux calibration per spectral resolution element.
     11
    912**Prerequisites**
    10 •       Authorize SHARK-NIR on the SX side.
    11 •       Atmospheric conditions: AO working conditions.
    12 •       Bad pixel map, Background or Dark, Flat-field, distortion map
     13- Authorize SHARK-NIR on the SX side.
     14- Atmospheric conditions: AO working conditions.
     15- Bad pixel map, Background or Dark, Flat-field, wavelength calibration.
     16
    1317**Procedure**
    14 •       Observe a dense field (e.g., a globular cluster) with accurate HST astrometry and a guide star bright enough (mag F860W < 11).
     18- Observe the spectrum of a featureless (standard) star at a similar airmass to that of the science target.

    16 •       Better than 1 mas over FoV.
     23- Better than 10% for absolute flux calibration and average residuals from telluric removal.
