Effelsberg: ----------- Effelsberg started ok, weather improving during night, some clouds and wind. Ef is running fine as well. The change times are also a bit too short for us, some 20-30 seconds might be lost. Weather is cloudy and windy, Tsys ~200K. (Next time need longer gap time 60 -> 100 sec). Yebes: ------ bad weather - rain, DBBC problems no data at all up to 06:55 UTC. from Pablo: Yebes has not gone well. It has been raining during the whole night. Besides I am so tired that I overslept and could not detect an error in the configuration of the experiment that has prevented recording the correct signal. The procedure from Uwe was totally correct, and the patching also, we tested the pointing and the Tsys some hours before the experiment (200 K). But the procedure in station.prc that does amplitude calibration switched the input of the IF to another one with no signal. Since the procedure is triggered in preob, just immediately after the settings, it spoiled the latter. Take into account we seldom use the DBBC because of the technical problems we have had with the COREs. This is going to change in the next weeks. If we used it extensively and I were not so busy and tired I believe we would not have had this problem. In conclusion, we have no data at all up to 06:55 UTC. In any case I doubt that the data we are recording now is worth it. It is completley overcast and raining. GBT: ---- despite earlier snow warning, GBT could observe Pico: ------ The sky is clear and the Tsys about 110K. Recording on time. Slew cycle from 3C273 to M87 is a bit tight, may loose a few seconds of recording. from Salvador: the IF assignation defined in the prc file is the opposite that we used in previous sessions and I understood it was fixed. The prc file defines ifa=1,agc... and ifb=4,agc.... The IF 1 means RCP and IF 4 means LCP, according with the assignation that we decided. Note added after fringesearch: only LCP, RCP is being overwritten, wrong dbbctrk commands in station procedure. GBT: ---- from Antab file: Tsys=70-100 K from Frank: And I am pleased to say that the typical Tsys that is calculated both for GA029 and BH186A is in the range 80-100K, which is reasonable for the GBT 86GHz receiver. The weather was very good for both runs, but there were windy conditions during GA029 which caused pointing problems. VLBA: ------ recording on wrong disks until 04:49. These disks will be shipped to Bonn after correlation of other experiment in Socorro: Here is list of the packs vsn used at each station for GA029.
