    1 == P3.15        Flux calibration (off-centered target observation) ==
     1
     2 == P3.15       Astrometry plate scale and orientation ==
    23•       **Phase**               :       3 
    34•       **Status**              :       Draft   
    45•       **Category**            :       Nighttime Science Calibration (C5)
    5 •       **Recurrence**  :       once at commissioning and then on request for deep                                              coronagraphic observations.
    6 •       **Duration**            :       20 minutes
     6•       **Recurrence**  :       every night starting from commissioning
     7•       **Duration**            :       1 hour
    78**Description**
    8 •       Flux calibration to allow contrast estimation between the central star and a close companion, by measuring the star flux out of the coronagraph
     9•       Determine the astrometry of the science frame. Deduce detector on sky coordinates & plate scale from RA & DEC of a known multiple stellar systems. This calibration is to be done for a reference setup.
    910**Prerequisites**
    1011•       Authorize SHARK-NIR on the SX side.
    … …  
    1213•       Bad pixel map, Background or Dark, Flat-field, distortion map
    1314**Procedure**
    14 •       On target, the same set-up as an observation on science target; AO closed-loop, ND for bright targets to prevent detector saturation, the star behind coronagraph centered and off-centered keeping the stop. The derotator mode should be tracking the field with possible adjustment of the angle to prevent the star from rotating around the coronagraph.
    15 •       Observe a star with the coronagraphic devices after an offset of 0.5” is applied.
     15•       Observe multiple system(s) with known characteristics without the coronagraph
    1616**Success criteria**
    17 •       Flux of the star measured within the accuracy of 0.1 mag
     17•       Image scale better than 5 mas (goal 0.5 mas) over FoV, image orientation better than 3 arcmin (goal 18 arcsec)
    1818**Notes**
    19 •       Same as activity 7.2 in AD4
     19•       Same as activity 7.1 in AD4
