    79**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
     10- Throughput calibration to obtain absolute flux calibration of science targets.

    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

    1317**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.
     18- Observe a spectro-photometric standard star of known magnitude with no coronagraph and required filters.
