Requests for Additional/Backup Target and Change of Set-up

Introduction and Policy

During run in Visitor Mode, you are expected to perform the observations described in the approved proposal. This includes the targets and the instrumental set-up.

In case the changes are not approved (or not requested), you will have to stick to the original targets and set-up. If these observations cannot be performed (e.g. because of high wind) or are useless (e.g. seeing significantly larger than the seeing constraint in the approved proposal), the telescope will be used by the observatory staff to perform Service Mode observations or Test/Technical operations.


Since July 2007, these requests have to be submitted exclusively using the following webform:

USD Target/Set-up change request form.

Have your P2PP ID and password ready, as well as your run-ID.

You will receive immediately an acknowledgement, and later a reply indicating whether the change is approved or not, and the telescope will be notified.
