    79**Description**
    8 •       This calibration is performed to calibrate the target star center with respect to the detector in order to provide a reference input for frame derotation and quadrant combination.
     10- This calibration is performed to calibrate the target star center with respect to the detector in order to provide a reference input for frame derotation and quadrant combination.

    912**Prerequisites**
    10 •       Authorize SHARK-NIR on the SX side.
    11 •       Atmospheric conditions: AO working conditions.
    12 •       Bad pixel map, Dark
     13- Authorize SHARK-NIR on the SX side.
     14- Atmospheric conditions: AO working conditions.
     15- Bad pixel map, Dark

    1317**Procedure**
    14 •       DM produce a pattern offset with four spots symmetric with respect to the star + AO closed-loop + coronagraph
    15 •       The required specifications of the corresponding image are a grid of at least 2x2 regularly spaced focal plane image peaks within 5 and 15 lambda/D with FWHM < 45 mas and separation precision < 6 mas.
    16 •       DM offset applied on target acquisition to produce a waffle image. Find the center of the four first-order diffraction peaks (cross geometry) to deduce the pixel corresponding to the center field.
     18- DM produce a pattern offset with four spots symmetric with respect to the star + AO closed-loop + coronagraph
     19- The required specifications of the corresponding image are a grid of at least 2x2 regularly spaced focal plane image peaks within 5 and 15 lambda/D with FWHM < 45 mas and separation precision < 6 mas.
     20- DM offset applied on target acquisition to produce a waffle image. Find the center of the four first-order diffraction peaks (cross geometry) to deduce the pixel corresponding to the center field.
