| 1 | == P3.12 Checking field-stabilized mode/bearing rotation service == |
| 2 | • **Phase** : 3 |
| 3 | • **Status** : Draft |
| 4 | • **Category** : Nighttime testing (functionality and operability) (C4) |
| 5 | • **Recurrence** : once at commissioning |
| 6 | • **Duration** : 40 minutes |
| 7 | **Description** |
| 8 | • The field stabilized mode or in other words, the working of the bearing tracking service will be tested. |
| 9 | **Prerequisites** |
| 10 | • Atmospheric conditions: AO working conditions. |
| 11 | • Authorize SHARK-NIR on the SX side. |
| 12 | • Targets (star cluster) near zenith and horizon (say airmass of 2). |
| 13 | **Procedure** |
| 14 | • Select the target near airmass 2. There should be stars spread across the entire SCICAM, preferably close to the edges as well. |
| 15 | • Start the bearing tracking services (field-stabilized mode). |
| 16 | • Take short-exposure images for a duration of ##minutes. |
| 17 | • Check if the positions of these stars. |
| 18 | • Repeat the same for the target close to the zenith. |
| 19 | • The above may be repeated for a target where the rotation of the bearing is in the opposite direction as of the above tested one. |
| 20 | **Success criteria** |
| 21 | • The bearing tracking service works well and the field is stabilized within the precision needed. |
