- | Cd Ho: Dual frequency setup required. Will need special DAS setup | + | The basic method and frequencies for this experiment are the same as for the v255 experiments in Dec & Sep 09 (and earlier). |
- | At Mp Pa: Run with both DAS \& Huygens | + | The purpose of these observations is to obtain the fourth epoch for proper motion/ |
+ | |||
+ | 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. | ||
+ | |||
+ | The Shanghai Sheshan 25m antenna has a new 6 - 6.8 GHz receiver and will attempt to join v255i from 18:08 - 23:15 UT, recording to Mark 5. The data will be shipped to Hobart on eSATA hardbox disk, for test correlation of the Shanghai-Hobart baseline on hex and assuming its OK the Shanghai data will then be transferred electronically to Curtin. | ||

+ | The 4 x 16 MHz bandpass setup requires feeding two separate LOs into IFP#1 and #2 on the DAS/frequency translator. | ||
