People: M. Giroletti, P. Malaguti
While searching unassociated sources in the EMS list using a VLSS-NVSS cross correlation, it became apparent that VLBI calibrators/fringe finders are not identified by the automatic association procedure, yet they could be good candidates: VLBI calibrators/fringe finders are typically bright, very compact radio sources.
There's at least a couple of lists that one can use:
- the VERA 22GHz Fringe Search Survey (Petrov et al. 2007)
- the VLBA and LBA Calibrator Survey (also known as VLBI global solution)
In the tables below, we report the list of matches between VERA/VCS and the unassociated sources in the EMS list. There is 19 sources from VERA (mostly on/behind the galactic plane) and as much as 69 matches with VCS. Note that there is some overlay between the two lists.
