Detailed information for Parkes, Mopra and the Compact Array antennas is included with the separate proposal forms for these telescopes. |
|||||||||||||||
12GHz may be available on only 1 ATCA antenna and by special arrangement only. | |||||||||||||||
Depending on ATCA configuration and phase-stability conditions, it may not be possible to tie together all ATCA antennas. | |||||||||||||||
Hartebeesthoek is readily available by special arrangement through the VLBI scheduler. | |||||||||||||||
At Hobart for S & X bands (13 & 3 cm) there are 2 possibilities: | |||||||||||||||
either a single polarization (RCP) S/X system (Tsys 650 & 750 Jy respectively) | |||||||||||||||
or a dual polarization S band (Tsys 840 Jy) and a dual polarization X band system (Tsys 590 Jy) | |||||||||||||||
Note 1: The Perth 27.5m & 15m antennas, the Alice Springs 9m antenna and the MOST are no longer routinely available for VLBI. |
|||||||||||||||
Note 2: Additional antennas may also be available in the Asia Pacific region by arrangement with the APT. | |||||||||||||||
Note 3: The S2 VCR tape recording system was decommissioned in Jan 2007. All recordings are on disk via LBADR and correlated on the DiFX software correlator. | |||||||||||||||
