For projects which have specific time constraints, an interface is available which will capture the various pieces of information required to schedule the observations. However, this is only available for those projects that require a single configuration as the time-constrained interface implies simultaneous observing and it is very difficult to guarantee this in practice. The interface allows two kinds of time-constrained observations:
- Specific dates - the SB will be observed during one of the specified dates. This will be useful for coordinating observations with another observatory or for observing objects that are only visible during certain time windows e.g. comets.
- Multiple visits - if the SB needs to be repeated several times, these can be specified individually, both in terms of a specific date, or a time relative to a previous visit. A good example of this observing mode might be the observation of a Gamma-ray Burst at various times after its discovery.
Reasonable margins on the requested times should be entered. If these are too restrictive then it will be difficult to schedule the SB executions. A text box is available if it is desired to give further information regarding the proposed time-constrained observing.
