Date | Time | Experiment / Event | S-band VLBI SEFD | X-band VLBI SEFD | Comment |
Jan 17 | 23.00 | Pointing | | | Pointing updated with +0.155 deg El offset |
Jan 18 | 17.00 | R1466 | 4844 | 5287 | |
Jan 20 | 18.30 | R4466 | 10679 | 18892 | No data after 01.55 UT until end due to problems with Az drive tripping out |
Jan 24 | 17.00 | R4467 | 5734 | 5231 | Missed scans due to Az drives 20.12 - 22.13 and 14.00 - 14.18 UT |
Jan 27 | 03.00 | Pointing | | | Check shows a 0.02 deg offset. Probably not significant and no model update made |
Jan 31 | 17.00 | R1468 | 6173 | 4886 | Drive problems. Scans from 16.09-16.27 missed |
Feb 01 | 17.30 | T2074 | | | DBBC freqs incorrect for VC13, VC14. Rapid drift in formatter-GPS offset. Some scans missed due to drive problems. |
Feb 02 | 18.00 | OHIG70 | | | DBBC freqs incorrect for VC13, VC14. All scans after 15.19 lost, drive problems |
Feb 03 | 18.30 | R4468 | 6540 | 6126 | Many missed scans due to drive problems |
Feb 07 | 23.40 | Pointing | | | Offsets observed: xEL = -0.003, El = 0.02. No update to model |
Feb 08 | 17.30 | OHIG71 | | | Frequencies OK. Multiple drive failures |
Feb 17 | 03.10 | Pointing | | | Pointing updated with +0.05 deg El offset following tightening of encoder mounting brackets |
Feb 17 | | PCFS | | | Problem with Az drives tripping was fixed (software bug) |
Feb 17 | 18.30 | R4470 | 5458 | 8699 | |
Feb 21 | 04.13 | Pointing | | | Offsets observed: xEL = -0.01, El = -0.015. No update to model |
Feb 21 | 17.00 | R1471 | | | |
Feb 24 | 01.15 | Pointing | | | Offsets observed on 1921-293: xEL = -0.005, El = -0.005. No update to model. Single-dish X-band SEFD looks good |
Feb 24 | 18.30 | R4471 | 4425 | 4601 | |
Feb 28 | | Pointing and calibration checks | | | Pointing looked good, Y-factors show S-band Tsys ~110K, X-band 90K |
Feb 28 | 17.00 | R1472 | | | Note clock jump at 02.53 UT |
Mar 03 | 00.00 | Tsys | | | Y-factor measurements repeated: S-band Tsys ~110K, X-band 85K |
Mar 03 | 18.30 | R4472 | | | |
Mar 06 | 23.00 | Antenna | | | Checked feed for water: appears dry. Tightened some SMA connectors (a few loose ones), sealed around S-band loop couplers, checked bolts on El encoder mounting |
Mar 07 | 01.00 | Tsys | | | Y-factors measured S-band Tsys 95-100K, X-band 83 K |
Mar 07 | 10.00 | Pointing | | | Pointing looks good, both axes |
Mar 07 | 17.00 | R1473 | | | |
Mar 15 | 04.00 | Pointing | | | Pointing offsets xEL = 0.008, El = -0.02. No model change made but need to watch El |
