摘要:This paper describes the development of a general-purpose software correlator code known as
Distributed FX (DiFX). The code was developed primarily to facilitate an upgrade of the Long
Baseline Array (LBA) network for Very Long Baseline Interferometry (VLBI) in Australia, enabling
an upgrade from the S2 tape-based recording system to a PC-EVN disk-based system. This
upgrade has brought 4-8 fold increases in bandwidth and greatly expanded the available correlation
parameter space. This expansion in correlator capability has led to a range of new science,
both with the LBA and other VLBI arrays outside Australia, and these applications are briefly
described.
