P3.15 Astrometry plate scale and orientation

• Phase : 3
• Status : Draft
• Category : Nighttime Science Calibration (C5)
• Recurrence : every night starting from commissioning
• Duration : 1 hour

Description

• Determine the astrometry of the science frame. Deduce detector on sky coordinates & plate scale from RA & DEC of a 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.
• Bad pixel map, Background or Dark, Flat-field, distortion map

Procedure

• Observe multiple system(s) with known characteristics without the coronagraph

Success criteria

• Image scale better than 5 mas (goal 0.5 mas) over FoV, image orientation better than 3 arcmin (goal 18 arcsec)

Notes

• Same as activity 7.1 in AD4

LBTO support

• SOUL-AO support
