Astrometric global solution rfc_2015b used all available VLBI observations at 8.6GHz and 2.2 GHz, as well at 5 and 22GHz from 1980.04.11 through 2015.04.07, in total 6034 observing sessions, including 419 observing sessions dedicated to the absolute astrometry surveys, such as

• 24 observing sessions of VLBA Calibrator Survey;
  
• 17 observing sessions of Densification of the VLBA Calibrator Survey (VCS7);
  
• 10 observing sessions of Densification of the VLBA Calibrator Survey (VCS8);
  
• 15 observing sessions of the Australian LBA Calibrator Survey;
  
• 94 observing sessions of the VLBI 2MASS radioastronomy project;
  
• 16 observing sessions of the VLBA Imaging and Polarimetry Survey (VIPS);
  
• 145 regular geodetic VLBA sessions under the RDV program;
  
• 13 observing sessions in 1FGL, 2FGL, and 3FGL AGNs at parsec scales;
  
• 3 observing sessions of VLBA Galactic Plan Survey;
  
• 1 observing session of the EVN Galactic Plan Survey at K-band;
  
• 14 observing sessions of the K/Q survey;
  
• 34 observing sessions of the VLBA calibrator survey for BeSSeL project;
  
• 2 observing sessions of the Bologna survey of near galaxies;
  
• 3 observing sessions of the VLBA survey of flat-Spectrum FIRST Sources;
  
• 3 observing sessions of the CJ snap-shot survey with the VLBA;
  
• 3 EVN observing sessions for densification of the ICRF
  
• 7 VLBA+EVN observing session of the survey of optically bright quasars;
  
• 11 VLBA observing session of the survey for parallax measurements;
  
• 2 observing sessions of the compactness of weak radio sources at high frequency survey
  
• 2 observing sessions of the VLBI Ecliptic Plane Survey
  

Positions of 9280 sources were adjusted in 6 least square solutions for X/S, X/C, 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_2015b catalogue in HTML form (23 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 6506 sources from this catalogue. Among 9280 sources, 5910 are classified as calibrators, 3218 are classified as non-calibrators with reliable positions and 152 are classified as non-calibrators with unreliable positions.
2. rfc_2015b catalogue in ASCII format. The catalogue contains source positions, their uncertainties, total VLBA flux density, the VLBA flux density of unresolved components.
3. rfc_2015b 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_2015b catalogue in blokq format. The catalogue contains source positions and their uncertainties. This catalogue can be used as a priori file for library and Mark5 VLBI analysis software package Calc/Solve.
5. Interactive VLBI calibrator search tool among sources in the rfc_2015b catalogue.

Astrophysics Information

1. 40,068 Images and calibrated uv data for 6566 sources at S, C, X, U, K, Q, and W bands in one tar.bz2 file (58 Gb). For some of the sources images for more than one epoch are available.
2. Single dish spectrum for 8660 sources from published results determined with the 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.
