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, named the IGS solution,
             IGS stations are adjusted in a separate, simultaneous adjustment
             with only the Goldstone PGGA station in common.  In the second
             solution, called the PGGA solution, all PGGA stations are processed
             (including Goldstone) with the IGS sites: Algonquin, Bermuda,
             Kokee Park, and Penticton. Thus, there are five common stations
             in each pair of solutions. We also include North Liberty,
             McDonald, and the BARD stations in the PGGA solution.
             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.
             Starting GPS Week 0746, we constrain the orbits computed
             from the IGS solution to 1 meter in position and velocity,
             for each GAMIT PGGA solution.
         (3) The PGGA solution starting GPS week 0748 uses ambiguity-fixed
             results (previous weeks used ambiguity-free results).
         (4) Starting this week we have switched over completely to IGS constants.
         (5) Starting this week we are distributing the new IGS earth
             orientation parameter format.
         (6) This week we are testing daily parameter estimates for translation
             of coordinate system (geocenter correction).
         (7) This week we are estimating polar motion and UT1 rate parameters
             in GAMIT and passing these on to GLOBK analysis.
         (8) PC connection problems at Monument Peak on days 173-174. Change of 
             Ashtech Z-12 firmware 1D00 (on day 182) appears to have solved 
             the problem.
