VLBI global solution LCS1_PRE8

Astrometric global solution LCS1_PRE8 used all available VLBI observations at 8.6GHz and 2.2 GHz as well at 22GHz from 1980.04.11 through 2011.09.19, 5230 twenty four hour sessions, including 7 observing sessions from the LBA Calibrator Survey, in total 8.9 million measurements of group delays.

Positions of over 6541 sources were adjusted in a single least square solution. Technical description of the solution is under preparation. The catalogue contains 759 objects that were targets in LCS experiments v254b, v271a, v271b, v271c, v271d, v271e, v271f, v271g, and v271h.

IMPORTANT! This page will be frequently updated as work on the catalogue will go forwards. Pay attention on the change log.

Astrometric Results

  1. lcs1_pre8 catalogue in HTML form (1.4 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.

  2. lcs1_pre8 catalogue in ASCII format. The catalogue contains source positions, their uncertainties, total LBA flux density, the LBA flux density of unresolved components.

  3. Table of 1102 estimates of correlated flux densities of 809 sources from v254b and v271a-h experiments. Some sources were observed in more than one experiment.

  4. Table of estimates of correlated flux densities of 68 sources from the K-band VLBI experiments v230a.
