 Probably best to contact me if you have interest in trying out the network-fed correlator, as you'll need to set up the sending side of things as well which isn't covered here. Probably best to contact me if you have interest in trying out the network-fed correlator, as you'll need to set up the sending side of things as well which isn't covered here.

-This is pretty simple - it gives links to the polyco file(s) containing pulse prediction information (see the program TEMPO for a description of the polyco file format), and specifies where the bin end-points are set. It also gives the option to "​scrunch"​ the binned data. If SCRUNCH is true, each bin is scaled by its corresponding weight and the bins are summed before writing to disk: thus only one "​bin"​ is recorded per time integration. This can be used to implement a matched filter for each pulsar, recovering maximum S/N. If SCRUNCH is false, each bin is written out separately and the weights are ignored. This mode is not well tested, and may have bugs.\\+This is pretty simple - it gives links to the polyco file(s) containing pulse prediction information (see the program ​[[http://​www.atnf.csiro.au/​research/​pulsar/​tempo/​ref_man_sections/​tz-polyco.txt | TEMPO]] for a description of the polyco file format), and specifies where the bin end-points are set.
