    79**Description**
    8 •       Determine the astrometry of the science frame. Deduce detector on sky coordinates & plate scale from RA & DEC of known multiple stellar systems. This calibration is to be done for a reference setup.
     10- Flux calibration to allow contrast estimation between the central star and a close companion, by measuring the star flux out of the coronagraph
     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, distortion map
     13- Authorize SHARK-NIR on the SX side.
     14- Atmospheric conditions: AO working conditions.
     15- Bad pixel map, Background or Dark, Flat-field, distortion map
     16
    1317**Procedure**
    14 •       Observe multiple systems with known characteristics without the coronagraph
     18- 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 angle adjustment to prevent the star from rotating around the coronagraph.
     19- Observe a star with the coronagraphic devices after an offset of 0.5” is applied.

     24- Flux of the star measured within the accuracy of 0.1 mag
