11A6/10 2011/05/30 Ku .../0.025 NGC4418, 3C286 (flux cal)
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)
Comments: Fair weather. Flux cal based on suspicious pointing result. Do not use. Pointing checked regularly.
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.
11A6/4 2011/05/08 C 0.008/... NGC4214, M82SW, Mrk231, 3C286 (flux cal)
Comments: Excellent weather. Ku-band receiver problem at start of run, so dropped down to C-band. Pointing checked regularly.
11A6/3 2011/05/07 Ku .../0.015 M82SW, NGC660, Maffei2, 3C48 (flux cal)

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).

8A21/9 2008/06/02 Ku 0.008/0.017 NGC3079, NGC5194, NGC3690
Comments: Weather very good. Pointing checked every 2 hours and found to be good to better than 10 arcsec. Nodding with 50 MHz BW used throughout.
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

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

7A15/9 2007/02/28 Ku 0.008/0.015 NGC2146, NGC1068
Comments: Weather very good. Partly cloudy and calm. No test source measurement done due to relatively short run. Pointing checked before each galaxy measurement and found to be good to 10 arcsec. Some ice on surface so had to use stronger pointing sources. Most distant was 13 degrees away.
