Dear Elaine,

  Yes, I am going to provide estimates of the correlated flux density.
I will do it after the final correlation results will be available 
(mid August?). Kee-Tae Kim and, some other individuals expressed their
their intention to generate images from these data. This will be also very
very helpful.

  Very good. This fantastic success rate is mainly due to a very efficient 
candidate source selection based on simultaneous spectra in the [5, 20] GHz
range. We are waiting for the next release of AT20G. We have enough candidate 
sources for v271a, but we need more high quality candidates for next 
experiments.

  I do not know whether you are aware of it. This year we observed in
four regular VLBA geodetic experiments a sample of 45 AT20G sources.
These are mainly the sources with projected flux density at X-band > 200mJy,
with the spectral index flatter than -0.5 and in the declination range 
[-30, -10]. The list is available at
http://lacerta.gsfc.nasa.gov/vlbi/rdv/at20g_cumul.list
Positions from rdv67 and rdv68 and maps from rdv67 experiments are avaialbe at 
http://vlbi.gsfc.nasa.gov/astro We are going to continue this work. 

Sincerely,
Leonid
