itrf00                  ITRF00-NNR reference frame
itrf00_northamerica     North American Reference frame, established
                        using the sites defined in SCEC CMM3.
                        The ITRF00 is used to designate that the file began
                        as a solution in ITRF 2000 NNR, but was rotated into
                        the best fitting North American frame...
                        The best-fit pole and rotation were performed
                        using Brendan Meade's BLOCK Modeling Code.

The following files are in a local reference frame where we hold the station
LUTZ (a BARD continuous station on the Bay block in the southern Bay Area) 
fixed and determine all velocities relative to that single station. 

LUTZ_farfault           BAVU1.01 relative to a stable LUTZ. 
                        All sites near the Hayward fault are excluded
                        from this file because they tend to make plots messy.
LUTZ_nearfault          Companion to above file containing the sites near
                        the Hayward fault.
LUTZ_fixedstation       The coordinates of LUTZ...
