FORS2 long-term calibrations monitor
how to execute
This is an overview of the current age of FORS2 long-term calibrations. These are calibrations
which are not triggered by science data but by the maintenance part of the calibration plan.
This list includes maintenance, technical and Health Check calibrations.
| type of calibration |
description |
validity (days) |
current age of last calibration (days) |
evaluation |
| DARK_low_gain_MIT | monthly set of 3 darks, 1800 sec each (low gain) | 30 | 9.2 | OK |
| DARK_high_gain_MIT | monthly set of 3 darks, 1800 sec each (high gain) | 30 | 9.3 | OK |
| DETECTOR_MON_high_gain_2x2_MIT | detector monitoring template (high gain, 2x2 binning) | 90 | 20.7 | OK |
| DETECTOR_MON_low_gain_2x2_MIT | detector monitoring template (low gain, 2x2 binning) | 90 | 20.7 | OK |
| DETECTOR_MON_low_gain_1x1_MIT | detector monitoring template (low gain, 1x1 binning) | 90 | 20.7 | OK |
| LADC_FLAT_monitoring | monthly LADC flat monitoring | 30 | 3.9 | OK |

| type of calibration: |
tag defining the type of calibration |
| description: | description of data |
| validity: | as configured (follows the definition in the calibration plan) |
| current age of last calibration | age of last calibration found, in days |
| evaluation: | recommended action
OK/green: within 30% of validity, no need for action;
soft REMINDER/yellow: within validity but less than 30%, refresh on next occasion;
REMINDER/yellow: outdated but less than 30%, refresh on next occasion;
REMINDER/red: outdated by more than 30%, refresh as soon as possible
nothing found in last 12 months: most likely a configuration error
