First HSC data release!

Hyper Suprime Cam Survey First Data Release!

The HSC collaboration has now completed the two years of an ambitious 300-night imaging survey using the Hyper Suprime-Cam (HSC) on the Subaru 8.2m telescope on Mauna Kea in Hawai’i.  HSC has a 1.8 deg^2 field-of-view (FOV), which is unique for an 8m-class telescope. The combination of the wide FOV and large mirror diameter gives us unprecedented survey power, allowing us to perform three nested
surveys.  The Wide survey layer will image ~ 1400 deg^2 in grizy to a depth of i~26 mag (5 sigma, point source). The 28 deg^2 Deep layer will go a magnitude deeper, providing a time-domain survey component.  Finally, the Ultra-deep layer will cover two HSC pointings (3.5 deg^2) to a depth of i ~ 28
mag, in addition to a narrow-band component to detect Ly alpha emitters out to z~7.

We just release our first set of data! This corresponds to about 100 square degrees of 5 band imaging to an i band magnitude of 26. Details can be found here.
