The second release of SPHERE (Spectro-Polarimetric High-contrast Exoplanet REsearch instrument) data processed by the High-Contrast Data Centre (HC-DC) is now available in the ESO Science Archive Facility. SPHERE is designed for high-contrast imaging, low-resolution spectroscopy, and polarimetric characterisation of extrasolar planetary systems. This release provides reduced IRDIS imaging data acquired between ESO Periods P95 and P109 (April 2015 – September 2022), including SPHERE consortium Guaranteed Time Observations.

The collection consists of 3,267 individual science images, of which 2,667 are newly released and 600 correspond to data previously included in the initial release, now available with improved target identification and contrast assessment keywords. The IRDIS instrument provides classical imaging (CI), dual-band imaging (DBI), and dual-polarimetric imaging (DPI) between 0.95 and 2.3 µm; polarimetric reductions are not included in the current data products.

Users can query and download the data via the ESO Archive Science Portal or through programmatic access.
The DOI assigned to this data collection is doi:10.18727/archive/79, and further details are available in the release description.
