Phase 2 Observations Preparation for Observing Period 109

Published: 22 Dec 2021

With the release of the La Silla Paranal telescope schedule, the preparation of Service Mode (SM) observations (Phase 2) starts. The deadline for the submission of the Phase 2 material for Period 109 observations is 3 February 2022.

Detailed information on Phase 2 observation preparation can be found here. Users are reminded to use the web-based p2 tool for Phase 2 preparation. Both La Silla and Paranal users can use the guidelines on the p2 help webpage.

New in P109: For Service Mode observations that use VLT or VLTI instruments on Paranal it is now possible to design more complex observing strategies in the p2 tool with nested scheduling containers. For example a science case that requires monitoring with relative time delays of concatenation of science+telluric OBs can be expressed as time-links of concatenations. For the VLTI imaging observations use of groups of pairs of science+calibrator is mandatory, such that the group defines the set of concatenations that contribute to the same image or uv plane.

Feedback on Phase 2 tools and documentation is welcome. Users can contribute to further improvements contacting the User Support Department (USD). Users should also contact USD if they require assistance with their Phase 2 preparations.
