P2.8 Looking for filter defects/artifacts + 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/artifacts using an internal calibration source (flat /on-axis PSF?) within the instrument.

Prerequisites

• NCPA measurement (within SHARK-NIR bench using internal sources) available.

Procedure

• Take the images of all the filters using internal calibration source lamps within the instrument to locate/find out the filter effects/artifacts.
• You may take short- and long-exposures to get better contrast of the features if required.
• 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.

MB: I wonder why this needs to happen in this phase. I would say it could be done at any moment with internal sources, except of course for the dichroic / LBT mirrors
