S# = session number, # = number of daily solutions
sig = standard deviation of weighted mean (unscaled)
wrms = weighted root mean square error (repeatability)
nrms = normalized rms (can be used to scale sig)

Remarks: (1) BARD (Bay Area Regional Deformation Array) is the acronym for the 
             Northern California permanent GPS array.  The receiver RINEX data
             can be accessed from the Northern California Seismic Data Center
             (NCSDC) via anonymous ftp as follows:
              user: brkseis20.berkeley.edu (128.32.146.106)
              password: anonymous
              cd /pub/gps/rinex/YYYY/YYYY.DDD
               (YYYY=current year, DDD= Julian day)
             Processed RINEX data from BARD (and PGGA) are available from the
             SIO archive in the 'solutions' directories
             (e.g. solutions/94data/086p)
         (2) Starting GPS Week 0739, we incorporated a distributed processing
             scheme for the PGGA and IGS analysis.  This consists of two separate
             GAMIT solutions.  In the first solution, IGS stations are processed
             in common with only the Goldstone PGGA station.  In the second
             solutions, all PGGA stations are processed (including Goldstone)
             with the IGS sites: Algonquin, Kokee Park, Richmond and Penticton.
             Thus, there are five common stations in each pair of solutions.
             The solution file (h-file) output of each solution are input to
             GLOBK to produce station positions, satellite orbits and polar
             motion.  That is, we now have 14 GAMIT solution files per week.
         (3) BARD stations BRIB and FARB added to PGGA analysis
         (4) Possible hardware problem at Vandenberg causing poor vertical
             repeatability.             
         (5) PRN04 reposition during 0:00 to 04:00 on Day 087
         (6) PRN07 not usable on day 090 and 091
         (7) AREQ relocation on day 089
