=====Data Processing=====

On December 07, 2020 Jon had an email discussion with Wael Farah. Wael is a SETI Institute employee and is developing the new SNAP board based correlator. He gave me some insights into the data we can expect from the ATA. 

===File Format===

The data will be in the Breakthrough Listen Raw Data Format. See https://github.com/UCBerkeleySETI/breakthrough/blob/master/doc/RAW-File-Format.md for an explanation.

The details are sketchy to me, even with Wael's explanation. So I need to investigate with some real data. He states:

  For a single antenna, parsing the full 4096 channels, and assuming 
  4bits real + 4bits imaginary, the maximum throughput for a single 
  snap board is 2 GBytes/s
  
Wael also suggested this file, it is just random static, but I can use it to get used to the format. https://storage.googleapis.com/ata_test_data/Luigi_turboSETI/guppi_59187_24580_120775_Unknown_0001.rawspec.0000.h5 : Careful, it is 3.8GB

Look at https://github.com/UCBerkeleySETI/blimpy and like for GuppiRaw. I think this is how you erad in the files.

===Data===

I'm trying to decipher the docs and figure out exactly what data we are presented with...

For now (Dec 08, 2020) the online breakthrough data is offline. Have to wait to get some. - JR
