P.A.
Mean position angle of feature with respect to the core component
Velocity P.A.
Position angle of velocity vector in degrees
Vector Motion Offset
Offset between mean position angle and velocity vector position angle in degrees.
Speed
Angular proper motion in microarcseconds per year
Speed (c)
Proper motion in units of the speed of light
Perp. Accel
Angular acceleration perpendicular to velocity direction in microarcseconds per year per year
Par. Accel
Angular acceleration parallel to velocity direction in microarcseconds per year per year
Ejection Epoch
Ejection (zero core separation) date
Reference Epoch
Date of reference (middle) epoch used for fit
t R.A.

a. Feature has significant accelerated motion.
b. Feature has significant inward motion.
c. Feature has significant non-radial motion.
d. Fit parameters are from MOJAVE Paper X .
e. Feature has slow pattern speed.
A question mark indicates a feature whose motion is not consistent with outward, radial motion, but for which the possibility of inward motion and its degree of non-radialness are uncertain.
