Legend: x - not available at present, p - planned, *? - available but Tsys not known.

$^1$ Detailed information for Parkes, Mopra and the Compact Array antennas is included with the separate proposal forms for these telescopes.

$^2$ 12GHz may be available on only 1 ATCA antenna and by special arrangement only.

$^3$ Depending on ATCA configuration and phase-stability conditions, it may not be possible to tie together all ATCA antennas.

$^4$ Hartebeesthoek is readily available by special arrangement through the VLBI scheduler.

$^5$ At Hobart for S & X bands (13 & 3 cm) there are 2 possibilities:

$\bullet$ either a single polarization (RCP) S/X system (Tsys 650 & 750 Jy respectively)

$\bullet$ 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.
