Re: LCS: v271a correlation is finished. Preliminary LCS1_PRE1 catalogue.

Hi Chris and Leonid,

   Thanks, Leonid, for the high quality positions of many sources.

   If you let me know where the aips data is (just before moving it to the
astrometry software), I can gather some flux information and insert it
in the table that you sent.  I don't think the u-v coverage is
sufficient for imaging and long and short baseline correlated flux
densities, but we can see.  Also, I suspect that the flux density scale
may have to be bootstrapped from the known flux density of some
sources.  With luck, the ATCA has been monitoring some of them.

   Also, the accuracies are extrememly good in declination, presumable
because the n/s baselines may be just as long as those for the VLBA. 
In fact, the combination of high accuracy RA's from the VLBA and DEC's
from the LCS will be great for sources between -45deg and -30deg. 
Finally, although the positions are absolute, I suspect they may be
tied to about ten apriori accurate positions of high quality sources
that were included in the run.  So, is it possible that there could be
small offset positions in RA and, especially DEC, that are not included
in the error estimate?

Cheers,  Ed
