| 1 | == P3.5 Check the acquisition **Procedure** == |
| 2 | • **Phase** : 3 |
| 3 | • **Status** : Draft |
| 4 | • **Category** : Nighttime testing (functionality and operability) (C4) |
| 5 | • **Recurrence** : once at commissioning |
| 6 | • **Duration** : 1 hour(s) |
| 7 | **Description** |
| 8 | • Verify the acquisition sequence for SHARK-NIR |
| 9 | **Prerequisites** |
| 10 | • Atmospheric conditions: should be able to see bight stars on sky (preferably close to zenith?). |
| 11 | • Authorize SHARK-NIR on the SX side. |
| 12 | • Suitable bright enough target (including the possibility of performing AO). |
| 13 | **Procedure** |
| 14 | • Start the acquisition sequence: collimating the telescope to reduce the aberrations, close the loop and produce better ASM flat, NCPA estimation using phase-diversity algorithm, close SHARK-NIR tip-tilt+NCPA loop, and check the PSF quality at SCICAM. |
| 15 | • Save telemetry (open and closed loop of the ALPAO DM). |
| 16 | **Success criteria** |
| 17 | • Successful acquisition sequence. |
| 18 | **Notes** |
| 19 | **LBTO support** |
| 20 | • Support from LBTI/LBTO? |
| 21 | • Presence of John Hill usually helps while collimating for first time. |
| 22 | • Steve Allenson (as the TO) will be a great asset too. |
| 23 | **Associated SHARK-NIR personnel** |
| 24 | • JF, LM, MdP, MM (from AZ), DV? |
| 25 | **Date performed and by whom** |
