[Pafgbt] PAF/GBT progress report

[Rick Fisher]

A short progress report on the PAF/GBT project:

Paul Marganian (in Green Bank) and I have written and tested the first 
version of the interface between the old ADLink PAF data acquisition 
system and the GBT monitor and control system.  First-draft instructions 
for starting the ADLink DAQ system and observing with it on the GBT can be 
temporarily found at:

Comments welcome.

The other major component yet to be added to the GBT control system for 
PAF testing is a coordinate system for offsetting the GBT position on a 
rectangular grid centered on a celestial radio source.

Adapting the GBT/ADLink interface software to the new BYU 
spectrometer/Correlator should be considerably easier than writing this 
first interface from scratch.

--------

Also, Richard Black at BYU sent me a sample raw data output file from the 
spectrometer mode of the new BYU spectrometer/correlator/beamformer along 
with initial documentation on this system.  Aside from a couple of 
detailed questions, it looks like we have read and plotted the first 
spectra correctly at NRAO.

Thanks to Paul and Richard!

Rick
