Great proposal!
If I can help for this proposal, I'm ready to help.

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.

The driver for some airspy to download is rtlsdr-spectrograph, I think you should build it from source since the debian packages are not ready yet.
There's the need for testers to work on the server/client configuration to connect to an rtl_tcp server.

Yes,
This is meant for automated observatories or who wants assets or models to compare with their observations.
This way observers can find or recognize objects or take them automatically into account for further investigation.
Spectra are also useful to determine distances or more complicated stuff like star masses or radial velocities.

Some of the code of INDI contains the needed functions, still not perfect but at least automated observatories can do some guess in-loco instead of having a client with the relevant processing delay times or effort.

Including a machine learning core into INDI needs some effort however, but having a ready models set could be a good start! smile.png

My proposal is for a repository of data and assets for the INDI drivers.
This stuff may be useful for automated stuff or as machine learning models.
this repository should contain various stuff:

  • star shape models:
    • airy patterns
    • deconvolution patterns
    • aberration patterns
    • double star models
    • starlight timeseries
      • scintillation timeseries
      • obscuration timeseries
      • novae timeseries
      • double variable timeseries
    • etc.
  • spectra models:
    • star class spectra
    • nebulae spectra
    • laboratory on-earth references (for redshifts)
  • crosscorrelation models:
    • double star models
    • AGN models
    • Zernike models
  • radioastronomy models:
    • radio spectra
    • pulsar timeseries
    • radar timeseries
Some volunteer should put some of this material into the new repository or take them from archive documentation.

Ilia.
