Positions of 7049 sources were adjusted in 5 least square solutions for X/S, X-band, S-band, C-band, and K-band solutions. Currently, this is the most complete catalogue of positions of compact radio sources. Technical description of the solution is available here.

Astrometric Results

1. rfc_2012b catalogue in HTML form (10 Mb). NB: loading the catalogue takes time, please be patient. The catalogue contains source positions, their uncertainties, estimates of the total VLBA flux density, the VLBA flux density of unresolved components, naturally weighted CLEAN images in postscript and in fits format at X and S-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. Images and estimates of correlated flux densities are available for 3714 sources from this catalogue. Among 7049 sources, 5868 are classified as calibrators, 1082 are classified as non-calibrators with reliable positions and 100 are classified as non-calibrators with unreliable positions. For the sources from the latter class, there is a probability > 0.001 that group delay ambiguities were resolved incorrectly, and as a result, their position may be off in a range of 0."1 to 5' from the reported coordinates.
2. rfc_2012b catalogue in ASCII format. The catalogue contains source positions, their uncertainties, total VLBA flux density, the VLBA flux density of unresolved components.
3. rfc_2012b catalogue in key-format format. The catalogue contains source positions. This catalogue can be used as a priori file for VLBI SCHED scheduling software package.
4. rfc_2012b catalogue in blokq format. The catalogue contains source positions and their uncertainties. This catalogue can be used as a priori file for Mark5 VLBI analysis software package Calc/Solve.
5. Interactive VLBI calibrator search tool among sources in the rfc_2012b catalogue.

Astrophysics Information

1. 28,853 Images and calibrated uv data for 4321 sources at S, C, X, U, K, Q, and W bands in one tar.bz2 file (33 Gb). For some of the sources images for more than one epoch are available.
2. Single dish spectrum for 6791 sources from published results determined with use of the CATS database. NB: the estimates of flux density are NOT simultaneous. Since the majority of sources are variable, these estimates of the spectrum are not always reliable. Estimates of spectrum for some sources may be wrong due to errors in the database of singe dish flux measurements.
