Priority

Approved targets will be assigned a priority flag as follows:

• priority A targets have high priority in the scheduling process. In case a pointing is terminated by an unforeseen reason (e.g. technical difficulty) an observation is considered as completed if the overall time spent on the target (including all the pointings) is larger than $70\%$ of the approved time.

• priority B targets are approved to cover more than the available time to optimize the observing schedule. Therefore, only a fraction of these targets will be observed in the present AO. In case an observation cannot be performed, the target will not be rescheduled in the following AO, if any.

• TOO targets. Although TOO observations have the highest priority in the scheduling process, they will be performed only if a valid trigger and a follow up program compliant with the approved protocol is verified during the AO for which they are submitted (Sect.2.2).
