Nobeyama Radioheliograph (NoRH) is a radio telescope dedicated to observe the Sun Frequency: 17GHz (Right and left circular polarization), 34GHz (only intensity) Field of view: Solar full disk Spatial resolution 10 arcsec (17GHz), 5 arcsec (34GHz) Temporal resolution: 0.1 sec (Event), 1 sec (Steady) As the NoRH is a radio interferometer, original data are sets of correlation values of all the combination of antennas. They correspond to the spatial Fourier components of the brightness distribution of the solar disk. In most cases, it is necessary to synthesize images from the original raw data.
