P1.12 Verification of the contrast for coronagraphic masks

• Phase : 1
• Status : COMPLETE
• Category : Daytime testing (functionality and operability) (C3)
• Recurrence : once
• Duration : 1 day

Description

• Verify the center mask algorithm, and calculate the rejection factor. Verify the contrast obtained for different sets of masks on the scientific camera.

Prerequisites

• SHARK-NIR is connected to the LBT network.
• Electronics cabinets on.
• The cryostat should be running and cooled down.
• Activity P1.0 (and, if required, P1.11) should be completed.

Procedure

• TBW

Templates

• SHARKNIR_gen_tec_PSFAlignment
• SHARKNIR_gen_tec_PupilApoAlignment
• SHARKNIR_gen_tec_PupilLyotAlignment

Success criteria

• The mask-centering algorithm works efficiently.
• The raw contrast estimated is within specifications for all the coronagraphic masks.

Notes

LBTO support

• Liquid Nitrogen refill is required in the cleanroom.
