 - **Phase**             :       3  
 - **Status**            :       Draft    
 - **Category**  :       Nighttime testing (functionality and operability) (C5) + Nighttime calibration (C6)
-- **Recurrence**        :       once at commissioning and then on request.
+- **Recurrence**        :       every night starting from commissioning
 - **Duration**  :       2 hours
 
 **Description**
-- Acquire a series of sky backgrounds from science images. A short sky background may also be useful for remaining deviant pixel removal. 
+- 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. 
 
 **Prerequisites**
 - Authorize SHARK-NIR on the SX side.
-- Atmospheric conditions: AO working conditions???
+- Atmospheric conditions: AO working conditions.
+- Bad pixel map, Background or Dark, Flat-field, distortion map 
 
 **Procedure**
-- Observe a blank field close to the science target (separation~10-20 arcsec) 
-- The same set-up as nighttime science observations, but AO is not running, and the coronagraph may be removed. A list of telescope offsets is added to reach an “empty” field and jitter. 
+- Observe multiple systems with known characteristics without the coronagraph 
 
 **Templates**
-- SHARKNIR_cal_SkyBackground (not released)
+- SHARKNIR_cal_Astrometry (not released)
 
 **Success criteria**
-- 10% accuracy (dependent on measurement frequency) 
+- Image scale better than 5 mas (goal 0.5 mas) over FoV, image orientation better than 3 arcmins (goal 18 arcsec) 
 
 **Notes**
-- Same as activity 7.6 in AD4
+- Same as activity 7.1 in AD4
 
 **LBTO support**
+- AO support
 
 **Date performed and by whom**
