    1  == P3.14        Sky background ==
     1 == P3.19       Distortion map ==
    22•       **Phase**               :       3 
    33•       **Status**              :       Draft   
    4 •       **Category**            :       Nighttime testing (functionality and operability) (C4)
    5 •       **Recurrence**  :       once at commissioning and then on request.
     4•       **Category**            :       Nighttime calibration (C5)
     5•       **Recurrence**  :       once every week starting from commissioning + on request.
    66•       **Duration**            :       1 hour
    77**Description**
    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.
     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.
    99**Prerequisites**
    1010•       Authorize SHARK-NIR on the SX side.
    11 •       Atmospheric conditions: AO working conditions???
     11•       Atmospheric conditions: AO working conditions.
     12•       Bad pixel map, Background or Dark, Flat-field, distortion map
    1213**Procedure**
    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.
     14•       Observe a dense field (e.g., a globular cluster) with accurate HST astrometry and a guide star bright enough (mag F860W < 11).
    1515**Success criteria**
    16 •       10% accuracy (dependent on measurement frequency)
     16•       Better than 1 mas over FoV.
    1717**Notes**
    18 •       Same as activity 7.6 in AD4
     18•       Same as activity 9.6 in AD4
    1919**LBTO support**
    2020•       SOUL-AO support
