Phase 2 Observing Preparation


Phase 2 is the step when users of ESO's telescope facilities prepare for their observations. These preparations slightly differ for those who have been granted Service Mode observations versus observers who will travel to the telescope for their Visitor Mode observations. The backbone of all observations (with the exception of APEX, see APEX Service Mode Preparation) are the Observation Blocks (OBs) which one prepares with the Phase 2 Preparation Tool, or P2PP.

Help and instructions for Phase 2 preparations is offered by different teams, depending on the nature of the observations, via web pages and email contact. Please choose one of the following links:
