    3 •       **Status**              :       Draft   
    4 •       **Category**            :       Nighttime testing (functionality and operability) (C5) + Nighttime calibration (C6)
    5 •       **Recurrence**  :       once at commissioning and then for each LSS observation.
    6 •       **Duration**            :       4 hours

    79**Description**
    8 •       Atmospheric calibration to remove telluric atmospheric features from the stellar spectrum and get absolute flux calibration per spectral resolution element.
     10- This activity will center the long slit.
     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, wavelength calibration.
     13- Atmospheric conditions: AO working conditions.
     14- Authorize SHARK-NIR on the SX side.
     15
    1316**Procedure**
    14 •       Observe the spectrum of a featureless (and/or standard) star at a similar airmass that of the science target.
     17- Point to known binary stars and then offset the telescope and the rotators to get to the nominal (known) position of the planet or introducing a bright speckle by using secondary mirrors at the same parallactic angle of the planet in order to align the slit.
     18- TBD
     19
     20**Templates**
     21
    1522**Success criteria**
    16 •       Better than 10% for absolute flux calibration and for average residuals from telluric removal.
     23- xxx
