VLTI Configurations Overview
New for P96
The offered AT quadruplets available for service and visitor mode in P96 are different from the ones offered in P94. The new configurations were chosen combining operational constraints and an optimized sky and u,v coverage. The P96 quadruplets are presented in the figure below, alongside two figures showing the sky and uv coverage for a 4h observation of a star at -15º.
Configurations offered using the Unit Telescopes:
AMBER is offered on all four available UT triplets:
Configurations offered using the Auxiliary Telescopes:
The users are requested to provide their preferred AT quadruplet in their proposal at phase 1. The quadruplet cannot be changed after proposal submission. In case of the 3 telescope instrument AMBER, the triplet used on sky is set by the OB preparation process in phase 2 (for service mode proposals) and during the run itself for visitor mode observations.
PIONIER is offered on the 3 following quadruplets:
AMBER is offered with the 12 unique triplets:
