Overall status: C config final days (using additional science hours in high pressure zone; working well); first science with hardware stacking; last meeting of the year next week. Reminder of EVLA operations shutdown: 24 Dec-25 Dec (32 hours); 31 Dec - 01 Jan (16 hours); C configuration will be extended through to 18 January.
Key dates:
Pre 08Jan: Call for Proposals for February 2011 Call (first for new semester based system; tentative)
08-12 Jan: AAS with special NRAO sessions: Perley: 7 presentations scheduled for the EVLA special session.
Array: Dhawan/Rupen: RF switch tests with rapid monitoring; issue still affecting; being replaced as identified. Looking at acquiring new switches to solve the problem in the long term.
WIDAR (Rupen):
Notes: BlB stacking testing (opens up RSRO project 10B-186); panoply of small but serious issues (CM communication; effing problem; etc).
Notes: Minutes from last meeting coming; meeting this week; 3c454.3 flux monitoring on-going.
High Frequency: Claussen: Weak calibrator tests; needed.
Mid Frequency (Dhawan):
Notes:
Low Frequency (Momjian):
Notes:
Observing Modes
Spectral Line (Goss/Ott):
Notes: Doppler: L302 seeing phase jumps for frequency shifts (Dhawan); bandpass stability monitoring data taken this week. Zeeman follow-up from Sault result ('before' data taken; after pending).
Spectral Line: Dhawan: Follow-up on frequency offset phase jumps characterization.
Notes: Discussions last week with Ransom; plans to piggy-back on phased-array testing in January; try to use CBE to create initial file (discussion on type of SDM, switching between de-dispersion mode and correlator mode). Paul to come for conversion from VDIFF to DSPSR format.
Satoko Takahashi (POC: Juergen Ott); area(s): continuum, mosaicing; 10B-126 (AT380): A Millimeter Study of the Embedded Star-Cluster in the Orion Molecular Cloud.
[Frail/Butler]: Enable restrictions based on proximity to sun; review OST weather trending.
[McMullin/Frail]: %REDWrite up disposition of RR items.
[McMullin]: Review/recover metrics for Priority 0 items.
[Perley/McMullin]: SPW/IF/BB lexicon and mapper
Development of WIDAR guidelines document (Michael)
List of known problems (can be used by OSRO commissioning team (van Moorsel)
Med Priority [Rupen]: X, Ku band subbands are inverted (IF 1 is labelled as IF4, IF2 as 3, IF3 as 2, IF 4 as 1). Noted that this had been tested but there were enough changes to warrant a re-do.
Med Priority [TBD]: Phase offsets within scans (phase jump at scan boundaries). R&L phase offset on some scans - probably L302 LO problem, needs tracking down. MR: Seen on EA07, EA25 (both RR and LL)
Med Priority [TBD]: Added. Phase change when frequency changes (needs to be tested).
Med Priority [TBD]: Anti-aliasing does not behave as advertised.
Low Priority [TBD]: First scan often bad.
Low Priority [TBD]: Phase (and amp) wobbles; long history.
