| Field name | Content | Examples |
|---|---|---|
| Scheduler | Type of scheduling to use. Default is to use the dynamic scheduler, so scheduling units are picked up automatically, but it is possible to specify fixed time scheduling. | Dynamic |
| time at | Run observations at this specific time. Only use this if really required, e.g., the target is also observed with another telescope. Specifying this option circumvents priority scheduling and should be used with care. | |
| time after | Minimum start time of this scheduling unit. Default: start of cycle | 2021-06-01 00:00:00 |
| time before | Maximum end time of this scheduling unit. Default: end of cycle | 2021-11-30 23:59:59 |
| time between | Only schedule within the time windows specified here. More time-windows can be specified by pressing the + button below. This can be used to distinguish observations that should run monthly be specifying a few days where these observations could run. | From: 2021-07-08 00:00:00 Until: 2021-07-10 23:00:00 |
| time not between | Do not schedule within the time windows specified here. More time-windows can be specified by pressing the + button below. | From: 2021-07-08 00:00:00 Until: 2021-07-10 23:00:00 |
| Daily | require_day : Day time observations. Run when the sun is higher than 10 degrees above the horizon at the Superterp. require_night : Night time observations. Run when the sun is lower than 10 degrees above the horizon at the Superterp. avoid_twilight : Avoid sunrise and sunset. Run when the sun is higher than 10 degrees above the horizon at the Superterp, or lower than 10 degress below the horizon. | |
| transit_offset | Offset in (UTC) seconds from transit for all target beams in the observation. Alternatively, use you can specify the reference pointing as the reference for transit. When the observation is split into shorted chunks to be observed at different LST ranges. Please take into account a one minute gap between subsequent observations. | from -7200 to 7200 from -7200 to -3600 from 3600 to 7200 |
| min_distance | Minimum distance to the Sun, Moon and Jupiter (latter mostly relevant below 30 MHz) in degrees (backend uses radians). Current default 30, or 28.64 degrees | Sun: 30 Moon: 30 Jupiter: 30 (< 40 MHz ) else 15 |
| min_elevation.target | Minimum elevation for all SAPs in the target observations | |
| min_elevation.calibrator | Minimum elevation for the SAP of all calibrator observations | |
| Reference pointing | If true, will be used for scheduling calculations taking into account the transit_offset Note: If used, the reference pointing direction should be identical to the tile beam pointing direction (for HBA). | enabled=false enabled=true |
Observations will by default also be scheduled only in the cycles connected to the project. ...
