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. |
