New Release of PESSTO public survey data

Published: 06 Aug 2015

New reduced data (spectra and images) resulting from the PESSTO Public Spectroscopic Survey are now available via the dedicated Phase 3 query interface at the ESO Science Archive Facility.

This release number 3 includes the EFOSC2 and SOFI spectra (1728 spectra in total) and the reduced SOFI images (392 images) obtained during the first two years (April 2012-April 2014) of PESSTO operations, for a total of 681 distinct transient objects. Also included in this release is the PESSTO Transient Catalogue, a catalogue of all PESSTO sources for which a meaningful spectral classification has been obtained so far (556 sources).

Furthermore, for the first time PESSTO photometric light curves are made available; this initial release of the PESSTO multi-epoch photometric catalogue provides light curves for 18 objects.

The PESSTO public survey data release (#3) is accompanied by a comprehensive description of spectra, images, and of the transient catalogue. A dedicated description of the lightcurve catalogue is also available. Instructions on how to read or display data in the ESO/SDP tabular data format can be found in the 1D spectrum data format help page.
