P3.11 Check the acquisition procedure

• Phase : 3
• Status : Draft
• Category : Nighttime testing (functionality and operability) (C5)
• Recurrence : once at commissioning
• Duration : 2 nights

Description

• Verify the acquisition sequence for SHARK-NIR

Prerequisites

• Atmospheric conditions: should be able to see bright stars in the sky (preferably close to zenith?).
• Authorize SHARK-NIR on the SX side.
• Suitable bright enough target (including the possibility of performing AO).

Procedure

• Start the acquisition sequence: collimating the telescope to reduce the aberrations, close the loop and produce better ASM flat, NCPA estimation using phase-diversity algorithm, close SHARK-NIR tip-tilt+NCPA loop, and check the PSF quality at SCICAM.
• Save telemetry (open and closed loop of the ALPAO DM).

Success criteria

• Successful acquisition sequence.

Notes LBTO support

• AO support
