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
Published: 18 Aug 2015
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.
