| 1 | == P3.3 Telescope control – telescope mode and offset == |
| 2 | • **Phase** : 3 |
| 3 | • **Status** : Draft |
| 4 | • **Category** : Nighttime testing (functionality and operability) (C4) |
| 5 | • **Recurrence** : once at commissioning |
| 6 | • **Duration** : 30 minutes |
| 7 | **Description** |
| 8 | • For the correct telescope mode for SHARK-NIR find the offset direction and magnitude. |
| 9 | **Prerequisites** |
| 10 | • Atmospheric conditions: should be able to see bight stars on the sky (preferably close to zenith?). |
| 11 | • Authorize SHARK-NIR on the SX side. |
| 12 | • Target maybe a pair of stars (not too bright) separated by ca. 1arcmin (known value) |
| 13 | **Procedure** |
| 14 | • Send preset to the telescope. |
| 15 | • Center one of the stars to the central pixel of SCICAM. |
| 16 | • Issue the right offset to get the other star at the same pixel in SCICAM. |
| 17 | • Return to the original star and verify the centering. |
| 18 | **Success criteria** |
| 19 | • The offsets produce telescope motions of the size and (particularly) direction expected. |
| 20 | **Notes** |
| 21 | • Steve Allenson can create a paddle for SHARK-NIR offset if this info is given to him. |
| 22 | **LBTO support** |
| 23 | • Support from LBTI/LBTO? |
| 24 | • Presence of John Hill usually helps while collimating for the first time. |
| 25 | • Steve Allenson (as the TO) will be a great asset too. |
| 26 | **Associated SHARK-NIR personnel** |
| 27 | • JF, LM, MdP, MM (from AZ), |
| 28 | **Date performed and by whom** |
