Starting calibrations in total power using Uranus. Mean pointing offsets: 3, -7 arcsec. After focus (best value -0.15), the best beam sizes obtained are around 13 arcsecs in 1mm and 17.9 arcsecs in 2mm. After that, we tried a beam map on Uranus. Opacity was about 0.3 and the humidity level very high (99%). The weather conditions are not so good, probed by the peak-to-peak variations of the baselines (up to +/- 5 Jy). We proceed with a calib_1scan on Uranus. Then we go to NGC7027 and do pointing and focus. Then calib_1scan to NGC7027, CRL2688, MWC349. Then we proceed to the quasar 2251+158 for pointing, focus and a beam map. Latest polar observations in July measured ~5 Jy at 3mm and ~2 Jy at 1.3mm for this source.
