+- **Category**  :       Daytime testing (functionality and operability) (C3)
+- **Recurrence**        :       once after instrument installation at telescope platform
+- **Duration**  :       0.5 day
 
 **Description**
-- Verify the efficiency of the mask-centering algorithm and the final contrast with SOUL-AO and artificial turbulence intruded at the ASM.
+- 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. 
 
 **Prerequisites**
-- RR is mounted on the SX side.
+- Authorize SHARK-NIR on the SX side.
+- Atmospheric conditions: AO working conditions.
+- Bad pixel map, Dark 
 
 **Procedure**
-- TBW
+- TBW+TBC
+- DM (ASM/ALPAO-DM?) produces a pattern offset with four spots symmetric with respect to the star + AO closed-loop + coronagraph
+- 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.
+- 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.
 
 **Templates**
+- SHARKNIR_gen_cal_StarCenter (not released)
 
 **Success criteria**
-- Final contrast produced for various seeing conditions matches the simulations.
+- Accuracy of 3 mas (goal 1 mas) 
 
 **Notes**
+- Same as activity 7.8 in AD4
 
 **LBTO support**
-- Authorize SHARK-NIR on the SX side.
-- RR is mounted on the SX side.
 - AO support
