VEGAS Team Meeting

Attendees: Ray, Jason, Mark, Richard, Paul, Randy, Glenn, Anish, Marty, Dan

Agenda:

1. mode 1/2 ripples and AGBT14A-437 shared risk report
2. ADC Calibration
3. Review of Jim Braatz velocity/frequency issues (ideally needs Anish, Amanda, Melinda, Jim Braatz, Bob Garwood)
   • Review of Bob Garwood KFPA side-band problem. Is this fixed? How do we test it?
     • Richard will contact Bob for clarification
4. 1. Status of blanking time / mixed mode implementation
5. Status of other “current issues”: https://safe.nrao.edu/wiki/bin/view/CICADA/CICADAGreenBankSpectrometerCurrentIssues
6. Status of shared-risk astronomical observations: https://safe.nrao.edu/wiki/bin/view/CICADA/CICADAGreenBankSpectrometerAstronomicalObservations
7. Plans for testing for this week.

Meeting notes:

1. mode 1/2 ripples and AGBT14A-437 shared risk report
   • particularly DURATION < INTEGRAT issue (Mode #4).
     • Needs Joe and the new switching signals in place to complete
2. ADC Calibration
   • simply loading files does not reduce noise - needs additional step
   • Reprogram the roach works so there may be extra steps need to recalibrate the ADCs with bof loads
     • on hold to complete after resolution of above - has a manager implication
3. Review of Jim Braatz velocity/frequency issues (ideally needs Anish, Amanda, Melinda, Jim Braatz, Bob Garwood)
   • Melinda needs to release a fix that Anish has evaluated
   • CRVAL issue resolved
   • Review of Bob Garwood KFPA side-band problem. Is this fixed? How do we test it?
     • Needs GBT mantenance/test time
4. Status of blanking time / mixed mode implementation
   • May be delayed by as much as two weeks by unplanned LO-1 work taking key resource
   • Richard will draft an astronomical/user requirement for desired config tool behavior
5. Status of other “current issues”: https://safe.nrao.edu/wiki/bin/view/CICADA/CICADAGreenBankSpectrometerCurrentIssues
6. Status of shared-risk astronomical observations: https://safe.nrao.edu/wiki/bin/view/CICADA/CICADAGreenBankSpectrometerAstronomicalObservations
7. Plans for testing for this week.
   • Dependent o LO-1 work
   • Can do some bank testing (Creager)
   • items to test when GBT becomes available
     • mode 1 testing
     • KFPA sideband issues
     • Streaming testing
     • Tests Joe needs
     • Patch Melinda's code and re-run Jim's test

- Commissioning activities should be getting charged to hardware support and testing (432510)

Account 432510

- scientists assisting with shared-risk commissioning should be charging an observer support account.

432540 for the most part. Accounts 142023 (GB-based staff) and 142013 (CV-based staff) for when you are helping with overarching observing support (not problem solving, VEGAS specific)
