The DiFX software correlator
All disk-based recorded LBA data is now corrrelated on the DiFX
software correlator developed at the Swinburne University of
Technology. LBA data was correlated using DiFX on
on the Swinburne supercomputer cluster,
under a service agreement with the ATNF in 2007 and 2008.
From 2009, the major correlator facility for the LBA National
facility operations is run under contract by the Curtin University
More details about LBA correlation are given on the
LBA wiki pages.
The DiFX software correlator is described in Deller, Tingay, Bailes and West 2007, PASP, 119, 318. See also the DiFX home page.
The S2 correlator
Until the end of 2006, all S2 tape-based recordings on the LBA were
correlated at the ATNF LBA hardware correlator. The S2 tape system was
decommissioned in January 2007 and all recordings on the LBA are now
on disks, using the LBADR recording system.
Details of the S2 correlator are included here for reference when examining archival LBA data.
