Since November 2018, the four Auxitiliary Telescopes (ATs) at VLTI are equipped with the adaptive optics NAOMI systems (annoucement).

ESO wishes to demonstrate NAOMI new capabilities with the PIONIER and GRAVITY instruments during a Science Verification period. 5 nights with the ATs will be devoted to the NAOMI Science Verification (SV) starting on May 7 2019.

All astronomers are invited to participate in this opportunity to demonstrate the improved capabilities of PIONIER and GRAVITY in terms of sensitivity (+1mag in limiting magnitude compared to the P103 call for proposal) and precision in visibility and closure phase (typically be a factor 2 to 3). Improved precision is important for targets with high contrast (e.g. a star+disk or star+faint companion, etc.) and/or highly resolved sources (i.e. low visibilities). These improvements require to full-AO correction, when the guide star is brighter than R=12.5.

A call for SV proposals has been issued and the community is invited to submit proposals for the NAOMI SV using this proposal template and associated LaTeX file.

The offered PIONIER and GRAVITY modes for NAOMI SV are the same as for P103 (see the GRAVITY and PIIONIER instrument pages). Here are the limiting magnitudes for GRAVITY (K band) and PIONIER (H band), for the best observational conditions:

GRAVITY Klim
single field & 
FT dual field "on-axis"
9.0
SC dual field "on-axis" 9.0+3.0
FT dual field "off-axis" 9.5
SC dual field "off-axis" 9.5+3.0
PIONIER Hlim
Free 9.0
Grism 8.5


The observations will be conducted in Service Mode by a dedicated team of ESO astronomers. The NAOMI SV team will be able to assist the successful PI¹s in the preparation and optimisation of the OBs on a best effort basis only. The collected data will be made available to the whole ESO user community.

GTO protected targets

The list of protected targets for the  VLTI instruments Guaranteed Time Observations is available for P103. Observations of targets protected by the GTO  will not be accepted for SV.

WARNING: all (raw) data and calibrations are public immediately after the observations. There is no proprietary period nor earlier data release to the PIs. See the VLT Science Verification Policy and Procedures for more details.

General Information

An integral part of the commissioning of a new instrument at the VLT is the Science Verification phase. SV programmes include a set of typical scientific observations that should verify and demonstrate to the community the capabilities of the new instrument in the operational framework of the VLT Observatory.
