The Survey

The South Galactic Cap U-band Sky Survey is an international cooperative project between National Astronomical Observatories, Chinese Academy of Sciences and Steward Observatory, University of Arizona, USA. We plan to observe the region of b<-30 deg and DEC >-10 deg, which is about 3700 square degree filed of the south Galactic Cap in U-band.

The SCUSS pointings are shown below. The blue stripes are SDSSII DR7 scan, including the Stripe 82; the green stripes are SDSSIII survey; The small black squares are our SCUSS poitings and the red squares are BATC fields.
