C-band: ONOFF data taken after the session, tl09c03.log ====================================================================== ====================================================================== F09C1: data_valid1 problem --> no tpicd in the log. ====================================================================== EP064A: Two "dips" in Tsys, source change. ====================================================================== N09C1: Don't understand the change in Tsys around 02:00 UTC??!! Can be seen clearly in the tpicid-values. ====================================================================== EW012A: "Noisy". A lot of off-source tpical measurements ====================================================================== GC031C: Reasonable? Did not remove anything. A lot of off-source tpical measurements ====================================================================== EP064B: BBC7 high?? True for other experiments. The problem is the large change in Tcal (as function of frequency). ====================================================================== EP065: Lost time due to problems with module. Schedule restart. Unclear why there is a sudden increase in Tsys around 07 UTC. Can be seen in the tpicd-values. Rain??? ====================================================================== 22 GHz: Data is opacity corrected. We do not have a noisediode here. We use the chopper wheel method to calibrate. ====================================================================== Data on Saturn during EVN 1, 2009, gave Saturn22GHz-EVN-Session1-2009.ps, gave 0.65 K. Astro gives 13.72 Jy. Thus, DPFU = 0.048 ====================================================================== ====================================================================== N09K1: antabfs.pl -caltemp -scan n09k1on.log Bad weather, some rain.a If I don't use the -scan option I get a lot of "ski-hills". Would be nice to test to take a caltsys before and at the end of each source change, at least if they are far apart as here. ====================================================================== EM059D: antabfs.pl -caltemp em059don.log Did not use the -scan option. Ski-hills can be seen at the start of the experiment. ====================================================================== N09K2: antabfs.pl -caltemp -scan n09k2on.log The schedule change resulted in that data_valid1 was not removed from the snp-file. Thus, very few Tsys-values. ====================================================================== L-band: Data is not opacity corrected. ====================================================================== N09L1: RFI! ====================================================================== EP064C: Some rain+RFI. ====================================================================== EM074: RFI. Source below elevation limit last scans. ====================================================================== EP064D: RFI. ====================================================================== EA039: Rain first hours. Warning!!! VERY bad calibration before 20:00 UTC due to RFI. ====================================================================== 5cm: Data is not opacity corrected. We use a noise diode at 5cm. ====================================================================== N09M1: Tsys looks strange between 12-14 UTC. ====================================================================== EM064D: BAD!!!! Could be due to the weather?????? WVR-data looks OK?!. ====================================================================== EM064E: RFI????? CHECK. Will try to monitor? ====================================================================== EM064F: Reasonable? ====================================================================== EM062B: Bad weather. Rain snow wind. Antenna stowed twice. ====================================================================== EM069D: Reasonable? ====================================================================== EM069E: STRANGE: edited away Tsys data around 5-6 UTC!! Looks more normal now... ANTAB-file with no edit, have a look at em069eon_noedit.antabfs and em069eon_noedit.antabfs.ps ====================================================================== EM071A: Some rain. Is the behaviour of Tsys from 5 UTC true?? ====================================================================== EB039B: RFI?? ====================================================================== EM069F: Lost time due to wind. A *LOT* of editing have been done. ====================================================================== 43 GHz: Data is opacity corrected. We do not have a noisediode here. We use the chopper wheel method to calibrate. ====================================================================== Data on Saturn during EVN 1, 2009 gave 2.4 K. Astro gives 52.37 Jy for Saturn. Thus, 0.046 K/Jy. :-( See Saturn-43GHz-EVN1-LCP+RCP-EL20-40.ps 0.046 0.046 ====================================================================== N09Q1: antabfs.pl -caltemp -scan n09q1on.log Looks OK. Interesting example where one REALLY should be carefull editing!! ====================================================================== GB065A: antabfs.pl -caltemp -scan gb065aon.log Looks OK. Another interesting example where one REALLY should be carefull editing!! ======================================================================
