资源简介：
SWIN files contain the VLBI fringe visibilities of an observing session (24 hours long or 1 hour long). The files are created by the International VLBI Service for Geodesy and Astrometry (IVS) correlation centers and constitute the raw output of the Distributed FX-style (DiFX) software correlator running on a Swinburne supercomputer. These data form the basis for the fringe fitting process and can also be used to make source maps of the observed quasars.
