Archival Data
Through diligent searching of the archives we already have NEP HSC data from the HEROES and AKARI-NEP projects, and CDFS data from a collection of various small projects. These archival data make up for nearly the entirety of the HSC time lost in 2018.
All data are being re-reduced at the IfA (by A. Repp & C. McPartland) using the latest photometric/astrometric calibrations from Pan-STARRS and Gaia, along with the latest version (6.7) of the HSC data reduction pipeline.
