| 1 | == P3.23 Wavelength calibration == |
| 2 | • **Phase** : 3 |
| 3 | • **Status** : Draft |
| 4 | • **Category** : Daytime calibration (C3) |
| 5 | • **Recurrence** : every night when LSS observing mode is used. |
| 6 | • **Duration** : 10 minutes |
| 7 | **Description** |
| 8 | • Determine the central wavelength of each pixel for the long split spectroscopy observing mode. |
| 9 | **Prerequisites** |
| 10 | • Authorize SHARK-NIR on the SX side. |
| 11 | • Atmospheric conditions: AO working conditions. |
| 12 | • Bad pixel map, Background or Dark, Flat-field, distortion map |
| 13 | **Procedure** |
| 14 | • This calibration is performed illuminating the slit with the spectral calibration lamps with at least 5 known emission lines; background exposures with lamps switched off required. |
| 15 | **Success criteria** |
| 16 | • LRS: 10 nm (goal 5 nm), MRS: 1 nm. |
| 17 | **Notes** |
| 18 | • Same as activity 7.10 in AD4 |
| 19 | **LBTO support** |
| 20 | • Support from LBTI/LBTO? |
| 21 | **Associated SHARK-NIR personnel** |
| 22 | • JF, LM, MdP |
| 23 | **Date performed and by whom** |
