Some comments on Onsala calibration, session 2, 2006. 

UHF: 
f06u1on: No valid Tsys - RFI  --> No ANTAB

n06u1on: No valid Tsys - RFI --> No ANTAB

ev015on: Done. Not so much RFI. 

gv018aon: No valid Tsys - RFI --> No ANTAB

gv018bon: No valid Tsys - RFI --> No ANTAB


18/21 cm: 

gm062bon: RFI in RCP between 14-15?? Note tracking problem at 15:00 UTC. 
          Note that there is a STRONG variation in Tcal as a function 
	  of freq. at 1260-1280 MHz for RCP in particular. Thus, a filter
	  as wide as 16 MHz does NOT give a good calibration.

f06l2on:  RFI at certain times ==> Some very high Tsys.   

n06l2on:  RFI at certain times. ==> Some very high Tsys.

ea035con: RFI, e.g. at 03:00 UTC. ==> Some very high Tsys.

es056on :  RFI at certain times ==> Some very high Tsys.   

5cm cm: 

f06m2on:  Some high Tsys between 13.10-13.20 UTC, RFI?? RCP higher Tsys than LCP.  VC03 dead. 

n06m2on:  Some high Tsys, RFI?? RCP higher Tsys than LCP.  VC03 bad. 

eb032aon: VC03 changed around 07:10 UTC. The new one failed to lock around 18:40 UTC!!! Keep
          it running manually. Some high Tsys, RFI??

ef015on: Tsys looks a bit "jumpy". Could it be due to frequent source change, see part of
schedule below?? Note that PREOB (==> TSYS) is done ONLY?? on the Target.
