| 1 | == P3.7 Estimate the instrument throughput == |
| 2 | • **Phase** : 3 |
| 3 | • **Status** : Draft |
| 4 | • **Category** : Nighttime testing (functionality and operability) (C4) |
| 5 | • **Recurrence** : once at commissioning |
| 6 | • **Duration** : 50 minutes |
| 7 | **Description** |
| 8 | • Knowing the magnitude of the acquired star, the throughput of the instrument is verified for all the scientific filters. |
| 9 | **Prerequisites** |
| 10 | • Atmospheric conditions: photometric. |
| 11 | • Authorize SHARK-NIR on the SX side. |
| 12 | • Photometric stars as targets for every filter. |
| 13 | • AO working. |
| 14 | **Procedure** |
| 15 | • Take unsaturated images of the photometric star for every science filter. |
| 16 | • Estimate the instrument throughput for every filter. |
| 17 | **Success criteria** |
| 18 | • The instrument throughput for every filter is estimated and note down. |
| 19 | **Notes** |
| 20 | **LBTO support** |
| 21 | • Support from LBTI/LBTO? |
| 22 | • Presence of John Hill usually helps while collimating for the first time. |
| 23 | • Steve Allenson (as the TO) will be a great asset too. |
| 24 | **Associated SHARK-NIR personnel** |
| 25 | • JF, LM, MdP, MM (from AZ), DV? |
| 26 | **Date performed and by whom** |
