    1  == P3.19       Distortion map ==
     1 == P3.14        Sky background ==
    22•       **Phase**               :       3 
    33•       **Status**              :       Draft   
    4 •       **Category**            :       Nighttime calibration (C5)
    5 •       **Recurrence**  :       once every week starting from commissioning + on request.
     4•       **Category**            :       Nighttime testing (functionality and operability) (C4)
     5•       **Recurrence**  :       once at commissioning and then on request.
    66•       **Duration**            :       1 hour
    77**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.
     8•       Acquire a series of sky backgrounds from science images, expected mainly when observing extended objects. A short sky background may also be useful for remaining deviant pixel removal.
    99**Prerequisites**
    1010•       Authorize SHARK-NIR on the SX side.
    11 •       Atmospheric conditions: AO working conditions.
    12 •       Bad pixel map, Background or Dark, Flat-field, distortion map
     11•       Atmospheric conditions: AO working conditions???
    1312**Procedure**
    14 •       Observe a dense field (e.g., a globular cluster) with accurate HST astrometry and a guide star bright enough (mag F860W < 11).
     13•       Observe a blank field close to the science target (separation~10-20 arcsec)
     14•       The same set-up as normal science observations but AO is not running and coronagraph may be removed. A list of telescope offsets is added to reach an “empty” field and jitter.
    1515**Success criteria**
    16 •       Better than 1 mas over FoV.
     16•       10% accuracy (dependent on measurement frequency)
    1717**Notes**
    18 •       Same as activity 9.6 in AD4
     18•       Same as activity 7.6 in AD4
    1919**LBTO support**
    2020•       SOUL-AO support
