P3.10 NCPA working and performance

• Phase : 3
• Status : Draft
• Category : Nighttime testing (functionality and operability) (C4)
• Recurrence : once at commissioning
• Duration : 12 hours

Description

• Evaluate the NCPA working and performance using the baseline approach, phase-diversity approach using the Wollaston prism & dual-band imaging, and measurement of NCPA using SHARK-NIR internal calibration sources.

Prerequisites

• Atmospheric conditions: ?
• Authorize SHARK-NIR on the SX side.
• AO working.
• Target(s) at different Zenith distances with different magnitudes?

Procedure

• Acquire star of a given magnitude. Start SOUL-AO.
• Check the working and performance of the NCPA (already calibrated) baseline approach. Take images at SCICAM.
• Check the phase diversity NCPA approach using Wollaston prism + DI-DBI (need to do on the spot, but script exists). Take images at SCICAM.
• Check the phase diversity approach using the internal calibration source (already calibrated). Take images at SCICAM.
• Repeat for a different star (of different magnitudes and for a different elevation of the telescope). It is also good to do this for different seeing conditions.

Success criteria

• ???
