Short requests are intended for short exploratory observations, such as checking calibrators or the feasibility of an observational setup, in preparation for a VLBI observation or proposal. Short requests are not intended as short scientific observations and will have no proprietary time; after correlation and pipeline calibration they become public through the EVN Archive.
Short requests must use standard observing and recording modes. They will be scheduled on a best effort basis. The observing time (<= 4 hours) should be justified in the request; shorter projects may be easier to schedule.
The format of short observation proposals should include:
- A brief motivation, up to 250 words,
- The coordinates of the target(s) and calibrator(s),
- The calibrator coordinates,
- The observing time justification,
- The frequency band,
- The GST range,
- Essential stations for the observation.
- any other information necessary for central scheduling by JIVE
staff, e.g. preferred phase-referencing cycle (in case the short observation runs during an e-EVN day)
The proposal must be sent via email to the EVN Programme Committee Chair, with the EVN Scheduler and the Head of Science Operations in JIVE in copy.
Disk observations:
-
Requested observing time is <= 4 hours.
-
Short requests can be submitted up to six weeks before the beginning of a session.
e-VLBI observations:
-
Requested observing time is <= 4 hours
-
Short requests can be submitted up to three weeks prior to any e-VLBI run.
