The LBA Calibrator Survey LCS-1
Here the Long Baseline Array (LBA) Calibrator Survey, containing 410
new sources not previously observed with very long baseline interferometry
(VLBI) is presented. The survey, based on four 24 hour LBA observing
sessions, fills the areas on the sky declination > -40°
The positions were derived from astrometric analysis of the group delays
at 8.4 GHz frequency bands using VTD
and Solve software packages.
The LCS1 catalogue of source positions, tables of correlated flux density
at three ranges of the lengths of projected baseline and plots of correlated
flux density versus the length of the projected baseline are
are available at this page.
Astrometric global solution LCS1 used 4 observing sessions from
the LBA Calibrator Survey,
as well as all all available VLBI observations at 8.6GHz and 2.2 GHz
and at 22GHz from 1980.04.11 through 2010.10.23, 4947 twenty four hour
sessions, including 27 observing sessions of the
VLBA Calibrator Survey,
in total 7.8 million measurements of

Positions of over 5000 sources were adjusted in a single least square solution.
Technical description of the solution is under preparation.
The catalogue contains 410 objects that were targets in LCS experiments
LCS1 catalogue in
HTML form (0.6 Mb). NB: loading the catalogue
takes time, please be patient. The catalogue contains source
positions, their uncertainties, estimates of the total LBA flux
density, the LBA flux density of unresolved components, naturally
weighted CLEAN images in postscript and in fits format at X band;
plots of the correlated flux density as a function of the
length of the baseline projection to the source plane; fits files
with calibrated uv data.
