- As of P96, for most VLT instruments, the former 'Seeing' constraint is now called 'Image Quality' inside the Observation Blocks. As before, you are expected to enter the requested image quality at the observed wavelength and airmass. This must be consistent with the V-band seeing at zenith you requested in your Phase 1 proposal. Conversions between seeing and image quality can be performed with the Exposure Time Calculator for the concerned instruments. The OB validation script of P2PP naturally takes this change into account.
- Preparation of the Service Mode observations for all Paranal instruments must be made with P2PP version 3 (P2PP3). The latest version of P2PP (3.4.2) incorporates changes required to work with 'Image Quality' instead of 'Seeing' (see above paragraph) and is able to communicate with the new unified Guidecam tool. P2PP3 also offers the possibility to encode the observing strategy using so-called scheduling containers.
- For preparation of Visitor Mode observations for all Paranal instruments web-based p2 application must be used. For more information please follow Visitor Mode Phase 2 Guidelines.
- Observation preparation for La Silla telescopes must be done using version 2.13.2 of P2PP. Version 2.13.1 is not usable anymore due to changes made to the ESO operational databases.
- Starting with Phase 2 preparation for Period 90, with P2PP3 it is now possible for a PI of an observing run to allow another user to create the OBs, READMEs, etc. using their own User Portal account. Learn more about the Phase 2 delegation feature on our dedicated P2PP page.
- As of ESO period 91, all observations of moving targets are fully integrated within the automated scheduling of service-mode observations at the VLT. To enable this, all observations of moving targets must specify the ephemeris file as a so-called VLT Parameter File (PAF) as well as the corresponding absolute time windows. More information on the requirements for the ephemeris file can be found at the Moving Targets procedure page.
