Recent developments of the SFXC software correlator

The SFXC software correlator has become the primary correlator for the EVN. Due to its nature a software correlator is much more flexible than a hardware solution, greatly simplifying the development of new correlator features. SFXC offers a number of new features which were not previously available to EVN users. These new features include: Pulsar binning and gating, multiple simultaneous phase centres, arbitrary spectral resolution, and spectral windowing. Furthermore SFXC has a number of space science features such as Doppler tracking phase corrections and a near field delay model. Currently under development is a phased array mode which has applications for pulsar and fast transient search experiments. The resulting time series are stored in PSRFITS format, which is widely supported by pulsar analysis software.
