A new release of the Public ESO Spectroscopic Survey for Transient Objects (PESSTO) is available. This release adds 1350 spectra and 383 images to the previously published PESSTO data. All the EFOSC2 (2851) and SOFI (226) spectra, and all the reduced SOFI images (775), obtained during the first four years (April 2012–April 2016) of PESSTO operations covering 1168 distinct transient objects, are available via the Phase 3 query interface at the Science Archive Facility.

The PESSTO Public Survey data release (DR3) is accompanied by a comprehensive description of the spectra and images. New versions of the PESSTO transient and lightcurve catalogues will become available in early 2017.

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.
