P3.7 Checking field-stabilized mode/bearing rotation service

• Phase : 3
• Status : Draft
• Category : Nighttime testing (functionality and operability) (C5)
• Recurrence : once at commissioning
• Duration : 2 hours

Description

• The field stabilized mode, or in other words, the working of the bearing tracking service, will be tested.

Prerequisites

• Atmospheric conditions: AO working conditions.
• Authorize SHARK-NIR on the SX side.
• Targets (star cluster) near zenith and horizon (say airmass of 2).

Procedure

• Select the target near airmass 2. There should be stars spread across the entire SCICAM, preferably close to the edges as well.
• Start the bearing tracking services (field-stabilized mode).
• Take short-exposure images for a duration of ##minutes.
• Check the positions of these stars.
• Repeat the same for the target close to the zenith.
• Repeat the same steps for a target where the rotation of the bearing is in the opposite direction.

Templates

Success criteria

• The bearing tracking service works well, and the field is stabilized within the precision needed.
