| 2 | • **Phase** : 3 |
| 3 | • **Status** : Draft |
| 4 | • **Category** : Daytime calibration (C3) |
| 5 | • **Recurrence** : once every month starting from commissioning. |
| 6 | • **Duration** : 20 minutes |
| 7 | **Description** |
| 8 | • Monitor detector gain factor, RON, and non-linearity over time. |
| 9 | **Prerequisites** |
| 10 | • Instrument and dome closed |
| 11 | **Procedure** |
| 12 | • This calibration is performed by reading the detector without any light illumination i.e. using an opaque position during 600s. |
| 13 | • Continuous extended source in the calibration; various ND; various integration times. CI in B_H. |
| 14 | **Success criteria** |
| 15 | • 5% expected accuracy. |
| 16 | **Notes** |
| 17 | • Same as activity 9.2 in AD4 |
| 18 | **LBTO support** |
| 19 | • Support from LBTI/LBTO? |
