A Real-Time Parallel-Processing Imaging System for Radio Astronomy
Overview ACSIS (Auto Correlation Spectrometer Imaging System) is a real-time data collection and reduction system intended for use with a 16 pixel receiver at the James Clerk Maxwell Telescope on Mauna Kea, Hawaii. At peak operating speed, the correlator connected to each receiver will generate an autocorrelation lag array of 8192 floating-point numbers every 50 ms, or 10.5 Mbytes of data every second. The ACSIS reduction system converts raw lag-data into calibrated radio-frequency spectra as the data are obtained. In mapping modes, these spectra are further inserted into a 3-dimensional data cube of image planes as a function of radio frequency. The reduction system should produce calibrated data of sufficient quality that further off-line processing is not required.
