Release of pipeline-processed PIONIER data

Published: 05 Apr 2017

As part of the agreement between ESO and IPAG (Institut de Planétologie et d'Astrophysique de Grenoble) to offer the PIONIER interferometric instrument attached to the VLTI in service and visitor mode for periods 96 to 99, IPAG has committed to process the raw data and deliver calibrated visibility data (squared visibility amplitudes and closure phases) to the ESO archive.

The scientific data obtained with PIONIER between 1 October 2015 and 1 January 2017 (ESO observing periods P96, P97, and half of P98) are now available as reduced data via the ESO Science Archive Facility. The data were processed by Jean-Baptiste Le Bouquin of IPAG, Grenoble, using the PNDRS pipeline v3.53 written and maintained by him.

The PIONIER calibrated visibility data can be queried and downloaded using the Phase 3 generic query form that provides access to all Phase 3 data. More details about the data are available in the associated Phase 3 data release description for PIONIER data.
