Meeting Notes:

VEGAS observation preparation Status:

1. half part of the IF band has poor SNR. why? is it fixed already? how to fix?
   • Resolved and ready for test
2. the start up problem:
   • Resolved and ready for test
3. 16 bins of the spectra have poor SNR. (an FPGA design problem).
   • Resolved and ready for test
4. valon locking problem.
   • Solved by a power cycle - inconsistent status between python GUI and laptop
5. what else needs to get fixed before we observe?
   • 12 second gaps
     • Resolved and ready for test
6. what tests should we do before we have enough confidence to start observing?
   • Test Pulsar
     • Ready to go - test 22-Jan PM
       • version with 'broken-up' observation data to later verify the ability to stitch together multiple observations
     • Broadband noise test 23 Jan AM
   • Known Pulsar - with gap to prove obs can be combined
     • Scheduled GBT time 23-Jan PM
     • On-Off continuum obs for sensitivity
   • Six hour data collection test period would be nice - can be done with test pulsar
