Field	Description
Common Name	Alternate name from 3C, 4C, CTA, NRAO, Ohio or other surveys
B1950 Name	IAU name based on B1950 coordinates (click on link to access NED database)
R.A. and Dec. (J2000)	Right ascension and declination coordinates of flat spectrum radio core from NED (epoch J2000)
Opt. ID	Optical spectral classification from Veron-Cetty and Veron (2003) and other catalogs: G = Radio Galaxy U = Unidentified (no known optical counterpart).
z	Optical redshift of host galaxy from NED
Radio Spectrum	Description of cm-wave (radio) spectrum: Flat = spectral index flatter than -0.7 Steep = spectral index steeper than -0.7 CSS = compact steep spectrum (steeper than -0.7 and size < 20 kpc) GPS/1 = gigahertz-peaked spectrum (GPS) with one-sided VLBI jets GPS/2 = gigahertz-peaked spectrum (GPS) with two-sided VLBI jets (a.k.a.. compact symmetric object)
EGRET ID	EGRET gamma-ray classification according to Mattox et al. 2001, Sowerds-Emmerd et al. 2003, 2004: Y = highly probable identification P = probable identification N = no gamma-ray counterpart detected by EGRET
V Mag.	Optical V magnitude from Veron-Cetty and Veron (2003) catalog.
Max. Speed	Maximum measured jet speed as of Sept 16, 2006. These values are subject to further refinement based on new MOJAVE data.
S_median @ 2cm	Median correlated VLBA flux density at 2 cm. These are calculated by taking the median of the integrated flux density in the VLBA map over all epochs on the particular source. The latter are published in Kovalev et al. 2005, AJ 130, 2473.
