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.

• Additional Targets: Make sure you have enough targets for the whole night. In case you need more to fill the night, additional targets must be requested and approved in advance.
• Backup targets:: Similarly, you should have a backup program in case the conditions do not permit your main program to be executed. In particular, keep in mind that strong wind often comes from the North, so backup targets to the South should be prepared. Backup targets must be requested and approved in advance.
• Change of set-up: in case you want to use an instrumental set-up not considered in the approved proposal, this must be requested and approved in advance.

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.

Procedure

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.
