PESSTO SSDR3 Released
In four years of operations, PESSTO has taken spectra of 1168 distinct objects. From this list, 161 supernovae (10 of which are super-luminous supernovae), 2 supernova imposters, 3 Tidal Disruption Events, 1 unclassified objects and 1 AGN were picked as interesting science targets and these were scheduled for follow-up time series EFOSC2 optical spectroscopy, with the brightest also having SOFI spectra taken.
In total SSDR3 contains 21.29GB of data. In total there are 2851 EFOSC2 spectra released. These include 1753 EFOSC spectra of the 168 PESSTO Key Science targets which are chosen for detailed follow-up. The remaining 1098 EFOSC spectra relate to 1000 objects for which we took classification spectra but did not pursue a detailed follow-up campaign. 224 SOFI spectra where also taken of the Key Science targets.
Total number of science files released in the various formats is described in the table below.
The release descriptions for the data products can be found here and further information can be found in the ESO news archive.
