 +===== Comments: =====
 +
 +Due to popular demand V490 has copied the basic strategy used for the V255 series of methanol maser astrometry experiments. ​ There are two different frequency setups, the "​ICRF"​ observations to calibrate the tropospheric delay has 2 IFs with different polarizations. ​ The second setup (the one used for the majority of the time) has a single IF with dual polarisation. ​ The times for the setup (mode) changes are given above.
 +
 +The purpose of these observations is to obtain the fourth epoch for proper motion observations of water masers in the SMC and LMC.
 +
 +===== 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 both Hobart and Ceduna the LOs should be set to 706 MHz (IFP#1) and 206 MHz (IFP#2) for the 4 x 16 MHz setup and 495 MHz for the 2 x 16 MHz setup. ​ For Hobart use 16.37 GHz as the Agilent frequency and for Ceduna use 17.47 GHz.  For the 4x16 MHz setup 880.2 and 900.2 MHz should give coherence in IF#1 and IF#2 respectively,​ while for the 2x16 MHz use 888.64 MHz to check coherence (these tones apply for both Hobart and Ceduna).
 +
 +The level into IF#2 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 v490d.1cm setup - it doesn'​t matter if the system temperature measurement doesn'​t work for the second 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. ​ The sources 0100-760, 0601-706 and 0530-727 should all be suitable for phasing the array (in addition to the fringe finder sources) and have been marked with the AUTOPHASE_DETERMINE intent in the vex file.
 +
 +The information below for Parkes has been copied from the v490b experiment and may need to be updated.
 +
 +Parkes LO can be controlled using the "​losched"​ command. It assume the initial setup has been made usign a normal lo_setup file. Run if as pksobs on joffrey:
 +
 +  > losched v490b.losetup
 +
 +''​v490b.1cm''​ frequencies at Parkes can be setup using the ''​2013Nov_13MMd.cmd''​ and ''​v490b.1cm-icrf''​
 + using ''​2013Nov_13MMe.cmd'' ​
