-===== Comments: ===== 
- 
-The basic method and frequencies for this experiment are the same as for the earlier v255 experiments (Mar 12, Nov 11 and earlier). ​ The frequency setup for this session is identical to v255q in March 2012.  As for the earlier experiments for the ICRF observations it is 2 IFs with different polarizations. ​ The times for the setup (mode) changes are given above. 
- 
-The purpose of these observations is to obtain the first epoch for proper motion/​parallax for G263.250+0.514,​ G305.202+0.208,​ G305.208+0.206 and G305.200+0.019 and the second epoch for proper motion/​parallax observations of the methanol maser sources G339.884-1.259,​ G339.681-1.208 and G339.682-1.207. ​   
- 
-The G263.250 observations run from 5-8:30 and 13:04-16:30 UT and should show a modest peak at a sky frequency of 6668.2 MHz.  The G305.21 run from 9:15 - 1215 and 17:15 - 20:15 UT should show a modest peak at a sky frequency around 6669.5 and the 339.88-1.26 run from 21 UT onwards should show a strong peak at a sky frequency of around 6669.7 MHz during these observations. 
- 
-During the ICRF runs we have sometimes had to exclude certain antennas (particularly Parkes) from observations of some sources in order to get a good spread of azimuths and elevations. 
- 
-===== Observing comments for each antenna: ===== 
- 
-==== Hobart, Ceduna :  ==== 
- 
-The 4 x 16 MHz bandpass setup requires feeding two separate LOs into IFP#1 and #2 on the DAS/​frequency translator. ​ For Hobart the LOs should be set to 468 MHz (IFP#1) and 810 MHz (IFP#2) for the 4 x 16 MHz setup and 810 MHz for the 2 x 16 MHz setup. ​ For Ceduna, if you set the agilent to 11.1 GHz rather than 11.4 GHz, then you can use the same LOs as at Hobart. 
- 
-The level into IF#1 will change significantly between the two setups. ​ Set the level into the DAS so that it is within range for both setups. ​ Setup the system temperature measurement so that it works for both IFs for the v255r.5cm setup - it doesn'​t matter if the system temperature measurement doesn'​t work for the first IF during the ICRF observations as these are only to calibrate the delay. ​ Please don't change the attenuation into the DAS when the setup changes as that may change the delay.  ​ 
- 
-==== Parkes, ATCA, Mopra :  ==== 
- 
-For the ATCA please phase-up antennas CA01 through CA05 for this experiment. 
- 
-""​++IMPORTANT:​++""​ 
- 
-The sources are all set at the ATCA for the last two hours of the experiment (i.e. 0200-0400 UT) 
- 
-Setup as for a 2p-4IF experiment (dual DAS with huygens cable for entire experiment) with DAS1 tuned to the lower frequency and DAS2 to the upper frequency. Use the feature in cdisko version 4 to automate the changes of channel selection as per the following table. 
- 
-| v255r.5cm | Channels 5-8 | 
-| v255r.5cm-icrf | Channels 1,2,7,8 | 
- 
-==== Parkes :  ==== 
- 
-0500-0614 UT, 0915-0951UT,​ 1610-1635 UT, 0110-0400 UT : Target sources not up at Parkes, Parkes not observing. 
- 
- 
-At Cd Ho Pa: Dual frequency setup required. Will need special DAS setup
