These corrections have been converted to nanoseconds and applied
to the VLA baseline file.  The corrected values were then
transformed as required by the EVLA system, expressed in meters
and inserted into the EVLA paramters database.  This was all
done around 2330 UT, March 17 2007.

It was not necessary to update the Modcomp baseline file,
but I think everything is easier if the Modcomp is in
sync with the EVLA data base.  Tools that I expect to be
able to use to feed AIPS baseline corrections into the
database were used to do this, but all the pieces have
not yet been joined into a whole.
