| K5 Software Correlator |
|---|
K5 software correlator was developed to correlate VLBI data with VSSP format observed by a K5/VSSP sampler. But it can now process any kind of data format, such as, Mark-5B, VDIF, ADS, OCTAD besides VSSP format. Software correlator is written in C, so that it can run on most of Linux distributions.
| Installation of Software Correlator |
|---|
PGPLOT or GNUPLOT should be installed in advance. If you want to use FFTW for FFT, FFTW3 package should be installed in advance.
| Software List |
|---|
As for software programs listed here except for "sdelay", you can get how to run by just executing a program without any option. You can get version information by executing a program with "--version" option.
