| EA055A | 2014-10-31 | Jun Yang | Success | None | The LO and BBC frequency setup was not correct until 19:45 UT. Because of the fixed bandwidth (250 - 500 MHz) of L-band filter, the LO frequency 1220 MHz in the vex file should be shifted down to 1000 MHz. |
| EA056A | 2014-10-26 | Jun Yang | Success | None | No known problems. |
| EA056B | 2014-11-02 | Jun Yang | Minor failures | None | The first 15 minutes were lost because of late starting of observations. This was due to a problem with switching on the antenna power. |
| EG084A | 2014-10-23 | Jun Yang | Failure | None | The wind was quite strong. Only got a chance to run the observation for about 40 minutes (13:29 -- 14:09 UT). |
| EG084B | 2014-10-27 | Jun Yang | Success | None | Cloudy night. No known problems during the observations. |
| EG084B | 2014-10-27 | Jun Yang | Success | None | Cloudy night. No known problems during the observations. |
| EP088G | 2014-10-21 | Jun Yang | Success | None | No known problems. |
| EP088H | 2014-10-28 | Jun Yang | Success | None | No known problems |
| ER030E | 2014-10-22 | Jun Yang | Success | None | None |
| ER030F | 2014-10-30 | Jun Yang | Success | None | No known problems. |
| ER030G | 2014-11-04 | Jun Yang | Success | None | No known problems. |
| ES072L | 2014-10-16 | Jun Yang | Success | None | No rain, while quite cloudy. Our 25m telescope is getting old. It could not track sources stably at 6.7 GHz, the highest working frequency, in particular if the wind direction is face on. There are some messages of "antenna, off-source" and "antenna, re-acquired" during the scans in the log file. |
| ES072M | 2014-10-17 | Jun Yang | Success | None | It was a cloudy day with a few short and light rain. |
| F14C3 | 2014-10-20 | Jun Yang | Failure | None | No observations due to high winds. |
| F14L3 | 2014-10-27 | Jun Yang | Success | None | None |
| F14L3 | 2014-10-27 | Jun Yang | Success | None | Successfully done with good ftp fringes |
| F14M3 | 2014-10-16 | Jun Yang | Success | None | No known problems. The FTP-fringe tests were successfully done. |
| F14X1 | 2014-11-03 | Jun Yang | Success | None | Clearly fringes to both MK5B+ data and Flexbuff data were found during all the FTP-fringe tests. |
| GA035A | 2014-10-28 | Jun Yang | Success | None | No known problems. The disk pack was sent to JIVE. |
| GB075B | 2014-10-20 | Jun Yang | Success | None | It was cloudy and quite humid. Once rain started, Tsys increased significantly. The weather was certainly not good for the 43 GHz observations. No other known problems. |
| GJ014 | 2014-10-22 | Jun Yang | Minor failures | None | The first 10 minutes were out due to a change of antenna gearbox. Proper Tsys data were not available until the noise source were reset to normal MK4 calibration mode. At 9:15 UT, there was an error: ERROR sc -24 setcl: Mark 5B syncerr_gt_3. CONSIDER using fmset 's' option to fix. I tried to run fmset for a few times, while, MK5B was busy and refused to sync time during the gap (no recording). |
| GJ014 | 2014-10-22 | Jun Yang | Minor failures | None | Switching on and off noise source had a long time delay (~20 seconds) in the first hour and so there were no Tsys measurements. After that, the bug was found and fixed by our software engineer. There was an error: 2014.294.09:15:50.22?ERROR sc -24 setcl: Mark 5B syncerr_gt_3, CONSIDER uisng fmset 's' option to fix. According to its suggestions, we tried to run fmset to fix it during the gap for a few times, while MK5B reported too busy to service request. |
| GP053B | 2014-10-20 | Jun Yang | Failure | None | Observations were only performed during 13:41 - 14:21 UT. Because of strong winds, the telescope had to be stowed in the other time. |
| GP053C | 2014-10-27 | Jun Yang | Success | None | No known problems. |
| GP053D | 2014-11-03 | Jun Yang | Success | None | No known problems. |
| N14C3 | 2014-10-22 | Jun Yang | Success | None | There were good fringes during the ftp-fringe tests. |
| N14L3 | 2014-10-30 | Jun Yang | Success | None | Good fringes were found during the ftp fringe tests |
| N14M3 | 2014-10-17 | Jun Yang | Success | None | Fringes were found in all the FTP-fringe tests. |
| N14Q2 | 2014-10-19 | Jun Yang | Success | None | Maser lines were seen in the extended ftp fringe test (N14QX). No clearly fringes were found during the FTP fringe tests of N14Q2. The weather was cloudy, certainly contributing high noise to the observing system. We checked PCal. It was clearly seen in our local monitor. LO frequency was properly set. Pointing was verified before the observations. No clock jumps were reported during observations. |
| N14X1 | 2014-11-04 | Jun Yang | Success | None | Good fringes were seen during all the ftp fringe tests. |
| EL050A | 2014-11-05 | None | None | None | None |
