 - **Category**  :       Nighttime testing (functionality and operability) (C5) + Nighttime calibration (C6)
-- **Recurrence**        :       every night starting from commissioning

 - **Duration**  :       2 hours
 
 **Description**
-- 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. 
+- Determine distortion map of science frame. Monitor distortion coefficient with time (weekly calibration) and measure the precise distortion of a given observation in any setup, if requested.

 **Procedure**
-- Observe multiple systems with known characteristics without the coronagraph 
+- Observe a dense field (e.g., a globular cluster) with accurate HST astrometry and a guide star bright enough (mag F860W < 11).
 
 **Templates**
-- SHARKNIR_cal_Astrometry (not released)
+- SHARKNIR_gen_mon_DistortionMap (not released)
 
 **Success criteria**
-- Image scale better than 5 mas (goal 0.5 mas) over FoV, image orientation better than 3 arcmins (goal 18 arcsec) 
+- Better than 1 mas over FoV. 
 
 **Notes**
-- Same as activity 7.1 in AD4
+- Same as activity 9.6 in AD4
