The Compact Array Broad-band Backend
This figure gives an overview of CABB, the Compact Array Broad-band Backend (Wilson et al. 2011), the heart of the Australia Telescope Compact Array (ATCA). CABB is the supercomputer that correlates the radio waves received by all six ATCA antennas typically every 10 seconds over 2 x 2 GHz of bandwidth. The wider the bandwidth, the more sensitive radio continuum and spectro-polarimetric observations can be obtained. Each wide band allows for 16 zoom bands that are sub-divided into 2048 channels each, providing excellent velocity resolution for spectral lines studies in the cm-regime (eg, HI, OH) and the mm-regime (eg, SiO, HCO+, CO).
