P2.8 Looking for filter defects/effects/features + Science detector calibrations repeat

• Phase : 2
• Status : Draft
• Category : Daytime testing (functionality and operability) (C2)
• Recurrence : once at commissioning
• Duration : 2 days

Description

• Finding the filter defects/effects/features using different lamps within the instrument.
• If required, this may be repeated for on-axis source from RR for selected or all filters while the AO loop is running (daytime)

Prerequisites

• If relevant, estimate and remove the NCPA using the phase-diversity method.
• RR mounted on SX side.

Procedure

• Take the images of all the filters using different lamps within the instrument to locate/find out the filter effects/defects/features.
• You may take short- and long-exposures to get better contrast of the features if required.
• This may be repeated with the on-axis source from the RR with AO running to check for any extra features arriving from outside SHARK-NIR but from LBT mirrors or the deployable arm.
• Repeat the science calibrations as done in P1.9.
• Perform the working of this monitoring activity Filter wheels reproducibility monitoring.

Success criteria

• All the filter images saved.

Notes

• The time dedicated to this activity has to be considered in combination with the next activity if needed. Parallelism is possible.

LBTO support

• Authorize SHARK-NIR on the SX side.
• RR mounted on the SX side.
• Support from LBT SW Team, LBTI/Arcetri team to run SOUL AO
