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

This release, No. 3, includes 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. One of these lightcurves (for SN2009ip) is shown in the figure.
The PESSTO release is accompanied by a comprehensive description of the spectra, images and the transient catalogue; together with a dedicated description of the lightcurve catalogue. 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.
