Phase II Observing Preparation

Phase II 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 II Preparation Tool, or P2PP.

Additional help with Phase II preparation is offered by different teams, depending on the nature of the observations:

• Service Mode observations (VLT and VLTI, La Silla 2.2m telescope): User Support Department
• Paranal Visitor Mode observations: Paranal Science Operations
• La Silla Visitor and Service (3.6m and NTT) Mode observations: La Silla Science Operations
• APEX Service Mode observations: APEX web site
