|---|---|
| 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. |
Right
ascension and declination coordinates of flat spectrum radio core (epoch J2000) |
| Opt. ID |
Optical
spectral classification from Veron-Cetty and Veron (2003) and other
catalogs: Q = quasar, B = BL Lac object, 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) |
| FERMI 2FGL | High confidence Fermi 2FGL association name (J2000) |
| R Mag. |
Optical R magnitude from USNO B1 Catalog (Monet et al. 2003) |
| 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. |
