New imaging data of the Public ESO Spectroscopic Survey of Transient Objects (PESSTO) released
PESSTO (Public ESO Spectroscopic Survey of Transient Objects) is a public spectroscopic survey that targets supernovae and optical transients brighter than 20.5m with the goal of classifying supernovae as close as possible to their explosion phase. Release version 1 contained more than 900 flux calibrated spectra for 298 distinct objects observed during the first year of the survey. Such spectra are now complemented with 234 reduced and calibrated near-infrared SOFI images for 22 transient objects. Images and spectra can be queried and downloaded from the ESO Science Archive Facility.
The PESSTO Data Release 2 is accompanied by a comprehensive description.
