Third Release of the PESSTO Multi-Epoch Catalogue

A new version of the PESSTO Multi-Epoch Photometric Catalogue provides photometric lightcurve coverage for the Public European Southern Observatory Spectroscopic Survey of Transient Objects (PESSTO) targets for which follow-up lightcurves have been completed.This catalogue complements and completes the DR4 release announced in March 2021.

Photometric lightcurves for a total of 95 objects are now provided, 65 more than in the previous release (the lightcurves of 2 previously released transients have been removed from the catalogue as they do not qualify as PESSTO key-science targets).

This PESSTO public survey data release (DR4.1) is accompanied by a comprehensive description of the lightcurve catalogue.

Data are available via the ESO Catalogue Facility, or programmatically⁽¹⁾, or via the Science Portal. Specifically, the catalogue preview gives instantaneous access to the histograms of all the catalogues columns. The programmatic link brings to a query example to find the lightcurve of SN2018ec, object shown in the image which also illustrates the serendipitous discovery of AT2018cux.
