Spectral
Energy Distribution Class, based on SED peak location, where LSP = Low-spectral peaked (< 1014 Hz), ISP = Intermediate-spectral peaked (> 1014 Hz and < 1015 Hz), HSP = High-spectral peaked (> 1015 Hz) Optical spectral classification from Veron-Cetty and Veron (2003) and other catalogs: G = Radio Galaxy U = Unidentified (no known optical counterpart). LPQ = quasar with fractional linear optical polarization consistently below 3% HPQ = quasar with fractional linear optical polarization above 3% on at least one occasion. Q = quasar with no available optical polarization data. B = BL Lac object. N = Narrow line Seyfert 1. |

| 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) GPS1 = gigahertz-peaked spectrum (GPS) with one-sided VLBI jets GPS2 = gigahertz-peaked spectrum (GPS) with two-sided VLBI jets (a.k.a.. compact symmetric object) |

Luminosity
distance
in megaparsecs, assuming Ho = 71 km/s/Mpc ,
Omega_lambda = 0.73 and Omega_m = 0.27. The angular scaling
conversion is given in parsecs per milliarcsecond. |
| Gamma-ray
loud? |
Fermi
LAT detection status: Y = associated in published Fermi-LAT team catalog, or in an ATEL N = not detected/announced by LAT team. EGRET gamma-ray classification according to Mattox et al. 2001, Sowerds-Emmerd et al. 2003, 2004, Casandjian and Grenier 2008, A&A 489,849 Y = highly probable identification P = probable identification N = no gamma-ray counterpart detected by EGRET TeV gamma-ray detection status as listed in TEVCAT |
| Kpc-scale
morphology |
Description
of
radio morphology on arcsecond scales: core: unresolved core component only. one-sided: emission on one side of unresolved core component. two-sided: emission on both sides of unresolved core component. halo: additional faint diffuse emission surrounding unresolved core. |
| Jet
Speed |
Maximum
measured speed
of any robust jet component in units of milliarcseconds per
year and the speed of light. For jets with at least five robust
components, a median speed is also listed. |
| Separation
vs.
time plot |
Plot
of
separation of fitted Gaussian components from the (presumed
stationary) core component versus time. These plots are subject to
change as new MOJAVE data are added. |
