VEGAS Team Meeting

Attendees: Ray, Joe, Jason, Melinda, Mark, John, Richard, Randy, Dan, Ray, John

Agenda:

1. Review of “mode 1-3 ripple” fix.
2. 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
3. Status of blanking time / mixed mode (continuum & spectral) implementation
   • Does Melinda have the information she needs for the config tool?
4. Status of other “current issues”: https://safe.nrao.edu/wiki/bin/view/CICADA/CICADAGreenBankSpectrometerCurrentIssues
5. Status of shared-risk astronomical observations: https://safe.nrao.edu/wiki/bin/view/CICADA/CICADAGreenBankSpectrometerAstronomicalObservations
6. Plans for testing for this week.

Meeting notes:

1. Review of “mode 1 ripple” fix.
   • Query in to Glenn for mode #1. Modes 2 & 3 also has artifacts that appear to be in the digital domain.
2. 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?
   • Delta frequency issues is being addressed in config tool
   • Wrong frequency computation is a problem with a passed manager parameter via config tool which was not CRVAL - needs to be CRVAL NOT passed via config tool for modes 1-19 (HBW & LBW1)
     • can be fixed in data taken to date - Amanda will test against Jim's data
3. Status of blanking time / mixed mode implementation
   • have tested on SRBS and should be ready for testing next week (includes multi-mode switching
   • Does Melinda have the information she needs for the config tool?
     • Use the 'solved' blanking algorithm and then derive the config tool requirements from the final solution
   • 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
4. Status of other “current issues”: https://safe.nrao.edu/wiki/bin/view/CICADA/CICADAGreenBankSpectrometerCurrentIssues
5. Status of shared-risk astronomical observations: https://safe.nrao.edu/wiki/bin/view/CICADA/CICADAGreenBankSpectrometerAstronomicalObservations
6. Plans for testing for this week.
   • Thursday -

Other

1. Ray wishes to make manager with data streaming as the baseline manager.
   • If testing is successful Thursday.

1. Please make sure to properly code your timesheets for the current time period and going forward.

- Software engineers should be using a GBT ops software CM&E account

Account 893252

- Electronic engineers should be using a GBT ops electronics CM&E account

Account 432510

- 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)
