Hi all,
For who's interested in radio interferometry:

I recently published  new domain: openvlbi.com
Here you can use a free crosscorrelator, by adding fits files compatible with the INDI FITS standard.
You can use an RTLSDR receiver or upload FITS files with low-samplerate observations, and the website will plot the correlations.
It's still at beta stage, and intensity interferometry only.

You can access with Google to the free service here: openvlbi.com/dashboard

Cheers,
Ilia.

That's very exciting, great job!
