• Velocity flags are almost identical to the coordinate flags:<br />

V Velocities from NNR-NUVEL1 or NNR-NUVEL1A model, from program<br />

NUVELO.<br />

A Velocities estimated without constraints in the normal equation combination<br />

step, from program ADDNEQ2.<br />

W Velocities estimated with constraints in the normal equation combination step,<br />

from program ADDNEQ2.<br />

N Estimated velocities for a station used to define a free network condition in<br />

the normal equation combination step, from program ADDNEQ2.<br />

I ITRF velocities.<br />

others Not estimated, not used, or unknown.<br />

• The tectonic plate information may be used to derive a new NNR-NUVEL1 or NNR-<br />

NUVEL1A velocity file for NUVELO after copying the file to a name with extension<br />

PLD (see Section 22.8.8).<br />
