P3.5 Check the acquisition Procedure

• Phase : 3
• Status : Draft
• Category : Nighttime testing (functionality and operability) (C4)
• Recurrence : once at commissioning
• Duration : 1 hour(s)

Description

• Verify the acquisition sequence for SHARK-NIR

Prerequisites

• Atmospheric conditions: should be able to see bight stars on 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

• Support from LBTI/LBTO?
• Presence of John Hill usually helps while collimating for first time.
• Steve Allenson (as the TO) will be a great asset too.

Associated SHARK-NIR personnel

• JF, LM, MdP, MM (from AZ), DV?
