    v1 v1  
     1 == P3.19        Sky background ==
     2•       **Phase**               :       3 
     3•       **Status**              :       Draft   
     4•       **Category**            :       Nighttime testing (functionality and operability) (C4)
     5•       **Recurrence**  :       once at commissioning and then on request.
     6•       **Duration**            :       10 minutes
     7**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.
     9**Prerequisites**
     10•       Authorize SHARK-NIR on the SX side.
     11•       Atmospheric conditions: AO working conditions???
     12**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.
     15**Success criteria**
     16•       10% accuracy (dependent on measurement frequency)
     17**Notes**
     18•       Same as activity 7.6 in AD4
     19**LBTO support**
     20•       Support from LBTI/LBTO?
     21**Associated SHARK-NIR personnel**
     22•       JF, LM, MdP
     23**Date performed and by whom**
