| 1 | == P2.7 Looking for filter defects/effects/features == |
| 2 | • **Phase** : 2 |
| 3 | • **Status** : Draft |
| 4 | • **Category** : Daytime testing (functionality and operability) (C2) |
| 5 | • **Recurrence** : once at commissioning |
| 6 | • **Duration** : 1 hour(s) |
| 7 | **Description** |
| 8 | • Finding the filter defects/effects/features using different lamps within the instrument. |
| 9 | • If required, this may be repeated for on-axis source from RR for selected or all filters while the AO loop is running (daytime) |
| 10 | **Prerequisites** |
| 11 | • If relevant, estimate and remove the NCPA using phase-diversity method. |
| 12 | • RR mounted on SX side. |
| 13 | **Procedure** |
| 14 | • Take the images of all the filters using different lamps within the instrument to locate/find out the filter effects/defects/features. |
| 15 | • You may take short- and long-exposures to get better contrast of the features if required. |
| 16 | • This may be repeated with the on-axis source from the RR with AO running to check for any extra features arriving from outside SHARK-NIR but from LBT mirrors or the deployable arm. |
| 17 | **Success criteria** |
| 18 | • All the filter images saved. |
| 19 | **Notes** |
| 20 | **LBTO support** |
| 21 | • Support from LBTI/LBTO? |
| 22 | **Associated SHARK-NIR personnel** |
| 23 | • JF, LM, MdP |
