e-VLBI status table

Advertised frequencies and array configurations

Frequency band	e-VLBI array
1.6-1.4 GHz (18-21cm)	Ar, Cm, Ef, Hh, Jb, Mc, On85, Sh (1.6 GHz), Tr, Wb14
5 GHz (6cm)	Ar, Cm, Ef, Hh, Jb, Mc, On85, Sh, Tr, Ys, Wb14
6 GHz (5cm)	Ar, Cm, Ef, Hh, Jb, Mc, On85, Tr, Ys, Wb1
22 GHz (1.3cm)	Cm, Ef, Hh, Jb, Mc, Mh, On60, Sh, Ys

The expected aggregate bitrate is 1024 Mbps with the following limitations. Shanghai and Arecibo are limited to 512 Mbps, Arecibo is further limited to 256 Mbps outside UT range 4-10. Medicina and Yebes are limited to 896 Mbps; in the 1024 Mbps mode the highest subbands are dropped. The effective data rate to the MERLIN telescopes (except for Jb1/Jb2) is 128 Mbps due to analog bandwidth restrictions. Availability of MERLIN outstations and Jb2 will be limited in 2009/2010 due to the e-MERLIN upgrade. Hartebeesthoek may be able to join in the second half of 2010.

The observing frequency in a session is decided based on proposal pressure

Arecibo is most useful for science observations in between 4:00-10:00 UTC (best connectivity)
*Arecibo is not available. Effelsberg is not available during daytime on 8-9 September 2010
**Shanghai is not available on 29-30 September 2010 (geo-VLBI). Effelsberg starts late (~17 UT)
***Shanghai is not available on 4-5 October 2010 (Chang'e observation)
