P1.11 Check the working of the internal NCPA routine and looking for filter defects/artifacts

• Phase : 2
• Status : Draft
• Category : Daytime testing (functionality and operability) (C2)???
• Recurrence : once at commissioning
• Duration : 1 day

Description

• Check the working of the internal NCPA routine. Finding the filter defects/artifacts using an internal calibration source (flat-field) within the instrument.

Prerequisites

• SCICAM cooled down.

Procedure

• Run the Phase-diversity routine using the images taken with the SHARK-NIR internal calibration sources to measure the NCPA within (excluding the deployable arm)
• Take the images of all the filters using the internal calibration source (flat-field) within the instrument to locate/find out the filter defects/artifacts, if any.
• You may take short- and long-exposures to get better contrast of the features if required.

Success criteria

• Internal NCPA routine works fine and the PSF shows improvement in its quality.
• All the filter images saved.

Notes

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