7.5m Radio Telescope Alt-az Mount Cassegrain-focus

The C-Band All Sky Survey (C-BASS), will map the whole sky in temperature and polarization at 5GHz. The primary aim of C-BASS will be to allow accurate subtraction of the Galactic synchrotron polarization from the data produced by CMB polarization experiments. This is a joint project of the University of Manchester, the University of Oxford and the Rutherford Appleton Laboratory in the UK, the Owens Valley Radio Observatory (OVRO) of the California Institute of Technology (Caltech) in the USA, and Rhodes University and the Hartebeesthoek Radio Astronomy Observatory (HartRAO) in South Africa.
