| Comments: Fair weather. Spent entire run on NGC4418. Pointing checked regularly. | ||||
| 11A6/9 | 2011/05/21 | Ku | .../0.025 | NGC4418, NGC4214, 3C286 (flux cal) |
| Comments: Fair weather. Maybe something at 2-sigma in NGC4418. Pointing checked regularly. | ||||
| 11A6/8 | 2011/05/21 | Ku | .../0.025 | NGC6921, NGC6701, NGC1144, NGC1365, NGC520, 3C48 (flux cal) |

| 11A6/7 | 2011/05/18 | Ku | .../0.025 | Maffei2, 3C48 (flux cal) |
| Comments: Fair weather. Devoted run to Maffei2 Ku-band and was duly rewarded! -2mK absorption. Pointing checked regularly. | ||||
| 11A6/6 | 2011/05/15 | C | 0.009/... | Mrk231, 3C48 (flux cal) |
| Comments: Fair weather. Devoted run to check of Mrk231 C-band spectrum. C-band Rx appears to be problem. Pointing checked regularly. | ||||
| 11A6/5 | 2011/05/09 | Ku | /0.015 | M82SW, NGC660, 3C48 (flux cal) |
| Comments: Excellent weather. Pointing before 3C48 measurements foobar, so 3C48 flux cal not usable. Pointing checked regularly. | ||||

| Comments: Raining. Pointing checked at least every 2 hours and found to be good to better than 10 arcsec. Had a bad position (mistake in epoch conversion) for NGC224S4. Do not use these data. NGC224S4C is correct position for Cohen etal (1979) (-42,0) position. Used OnOff 50 MHz BW and offpos -60 arcmin in (Az,El). | ||||

| 8A21/8 | 2008/05/16 | C | 0.011/0.05 | NGC224 |
| Comments: Tail-end of a weather system forced drop-down to C-band. Pointing checked before all measurement sets and found to be good to better than 10 arcsec. Note also that I am using a -15 arcmin OFF position in Az (30 arcmin was probably unnecessarily far). | ||||
| 8A21/7 | 2008/05/14 | C | 0.014/0.07 | NGC2903 |
| Comments: Impending bad weather forced drop-down to C-band. Pointing checked before all measurement sets and found to be good to better than 10 arcsec. Note also that I went from using a -30 arcmin to a -15 arcmin OFF position in Az (30 arcmin was probably unnecessarily far). | ||||
| 8A21/6 | 2008/05/12 | Ku | 0.012/0.05 | NGC2903 |
| Comments: Cloudy but calm. Weather slowly improving as run progressed, but in fact pretty marginal for Ku-band. Pointing checked before all measurement sets and found to be good to better than 10 arcsec. | ||||
| 8A21/5 | 2008/05/08 | C | 0.013/0.07 | NGC598 |

| Comments: Snowing at start. Apparently some snow on dish/feed at start as could not get a good focus for VIIZw31 and UGC02369. Finally got a good focus before observing NGC1022. Best focus value quite close to 0.0, which was the assumed value when failed fit encountered, so inability to check focus likely not a problem. Pointing checked before most galaxy measurements (if next galaxy was near previous, didn't bother to check pointing) and found to be good to 10 arcsec. | ||||
| 7A15/13 | 2007/03/05 | C | 0.008/0.020 | NGC6701, Mrk331, VIIZw31 |
