Overall status: In D configuration (all antennas moved as of the 26th; end of D is 27 December). Some lurking issues under correlator; testing focus is on 3-bit.
Key dates:
26 Sep - 27 Dec: D configuration
Visitors:
Michiel Brentjens: 11 Jun - 11 Nov (Holography; characterizing polarized beams)
Hardware status and updates (Langley, Perley, Rupen)
Array (Perley/Langley):
Antennas: EA25 to MP (this week); return to array next week (10 Oct); EA19 is next in.
Receivers:
EA24 for first L-band solar capable Rx - pushed to 26 Oct.
Perley: RF Switch testing ongoing.
Calibration (Perley): Gain compression/expansion ongoing (Hayward).
Holography (Brentjens): Notes:
WIDAR (Rupen):
Notes (Rupen/Sowinski): On the sky acceptance document sent to Penticton; X1Y2 issue being investigated; currently test and remove/reboot as needed. Some oddities with THOL scripts (attenuators not being set properly); under investigation; some Ka-band oddities (removed from consideration last night - work today on this). 3-bit testing is the prime focus.
NOTE: Please cc me on submitted tests so that it can be assigned the appropriate priority!
Commissioning priorities for the week (McMullin, Chandler); Note: Change for Mondays in D configuration - dedicated to science operations/planned commissioning tests.

Issues Affecting Science Observing:
Correlator: [Rupen/Carlson w/ Momjian/Sault] V stokes issues.Status - next week.
Correlator: [Pokorny/Rupen/McMullin] time mislabeling in SDM data (non-synchronous operation between correlator dumps and CBE can require additional 1/2 integration time padding for online flags). .Needs close-out testing (Michael-update activation time testing).
Correlator: [Clark/Carlson] Delay rocking across bands. (October)
Array: [All] Zoo of other effects (some data are very good, some still seeing antenna-based IF/Polarization issue).
