Overall status: B configuration move ongoing. Not strong science need during the move so ideal time for testing efforts. Some stability loss recently with hardware/software updates.
Call for proposals (Claire): 193 EVLA proposals! (normally 120-130) - first for semester system. March 22nd for technical reviews. End of May for notification.
ApJ Special EVLA Issue: 53 responses; there will be a note in the e-news that extends interest to 15 February; estimates are that we'll get 75% of those articles. Instructions/timeline to come (expect mid-April deadline for publishing in June/July).
09-23 Feb: 4-band test installation
14-18 Feb: Meerkat visitors (Operations)
16 Feb: Correlator Fire Suppression tests
07-10 Mar: New Worlds, New Horizons (Santa Fe)
07 May - 15 Jun: 4-band science observing
05 Jan - 06 Apr: John Cannon sabbatical at DSOC
22 Feb - 08 Mar: Sonja Vrcic (Correlator)
28 Feb - 28 Mar: Bob Sault
Report from Dish Verification Meeting
DVA1 - Dish Verification Antenna 1 (SKA TDP=technology development program) - work toward a Pathfinder SKA prototype; Conceptual design review - get recommendation on whether to proceed or kill it (i.e., don't build an antenna). Napier, Woody, DeBoer, Goldsmith - recommended: significant technical design progress to warrant proceeding. NRAO leadership needed during construction phase of this project; needs an agreement between Fred/Jim Cordes (Cornell); Bob will write MOU. Rick notes: they are looking for site for construction for this summer (20 GHz top frequency - 15 m offset (15x18m)). Barn is not big enough. Needs a building to construct the dish.
Commissioning priorities for the week (McMullin, Chandler)
Single maintenance day week:
0900-1700 Testing/software development time
1800-0900: Science operations
Wed: Maintenance day
Issues for Science Observing:
Correlator: fshift sub-band anti-aliasing causing phantom spectral lines when using recirculation for narrow bands (only worry if Michael has to prep your file)
Correlator: Missing/mislabeled scans in data sets (small percentage but recurring).
Correlator: time mislabeling in SDM data (non-synchronous operation between correlator dumps and CBE can require additional 1/2 integration time padding for online flags.
Construction: RFI sweep at Ku, K, Ka, Q pre-requisite for high pass filters for use with L301.
Calibration: Switched power heuristics for reduction.
Array/Construction: Dhawan/Rupen: RF switch issues; new set coming to be tested.
Correlator: Delay rocking across bands.
Correlator: Subset of BlBs misbehaving (only affects hardware stacking modes)
Array: Amplitude wobbles seen on subset of antennas; phase jumps at scan boundaries also seen on subset of antennas (Ka, Q bands only thus far).
*Correlator*: missing sub-bands (initially thought tied to the station board upgrades; backed out); still occurring through 29 Jan.
Hardware status and updates (Langley, Perley, Rupen)
EA16 to array on 01 Feb(?); EA13 to AAB on 01 Feb(?).
CASA Update (new functionality available/issues/enhancements):Notes (Miriam): casapy-test is fixed and recommended (fix affected polarization angles). FO noted that he is still having some issues with UVFITS. If have issues with missing scans see CAS-2779 for information.
AIPS Update (new functionality available/issues/enhancements): Notes: Eric is working more on comparing weights; currently TYAPL and REWAY generate different weights (different by an order of magnitude). Behaviors are self consistent.
SDM Update: Notes:Continuing work to establish paths for CASA/AIPS use of switched power/cal device tables.
