Catalogue was created by Leonid Petrov ( lpetrov@localhost )
at 2012.04.17-22:08:12
with using program rfc_outcat version of 2012.04.17
This catalogue contains source positions and estimates of flux density from
reanalysis of VLBI experiments under absolute astrometry and geodesy
programs at the VLBA, LBA, and EVN in 1994-2012, as well as other VLBI
experiments under geodesy and absolute astrometry since 1980.04.11 through
2012.04.02, in total 5381 experiments.
In total, 9.5 million values of group delays were used in the solution.

Note (1):
C = calibrator, i.e. the semi-major axis of the inflated error ellipse is
less than 5 mas and more than 8 good pairs of X/S group delay
measurements are available;
N = non-calibrator with reliable coordinates, i.e. does not fit the
condition to be considered as calibrator, but has more than 8 good
group delay measurements at X or S band;
U = non-calibrator with unreliable coordinates, i.e. does not fit the
condition to be considered as calibrator, has less than 8 detections at
any band, and therefore, there is a risk that group delay ambiguities
were resolved incorrectly.
Note (2):
- = no data in the following column present.
< = upper limit of the flux density is presented in the following column.
Note (3):
X = central frequency 8.6 GHz;
S = central frequency 2.3 GHz;
X/S = Both bands with central frequency 8.6 and 2.3 GHz.
Note (4):
a = 27 known sources which previosly were observed with a priori errors > 30";
r = 68 sources observed in VCS1-2 with 64 Mb/s rate, which yielded 1-9 obs;
v = 139 leftovers from the VCS5 list;
i = 30 IDV sources with flux density average > 130 mJy.
