Guerrero Baseline Results

All campaign data for  Guerrero are publically archived
at UNAVCO.  All continuous data collected with NSF
funds are also archived, with additional UNAM data
available from the CONCYt PI, Vladimir Kostoglodov.

I'm archiving solutions computed with GIPSY precise point
positioning (ITRF2000) and ambiguity resolution.  
The baselines are defined in the XX and lines of the file
(YY denotes end of baseline).
The baselines are relative to MDO1, with the local
ENV frame defined at the local site.   The data format is time, east, esig,
north, nsig, vertical, vsig, in cm.   Please keep in mind that these
formal errors are not realistics, as they are based on the assumption
that the orbits and satellite clocks are perfectly known (the precise
point positioning assumption).  

If you wish to use these solutions, you are required to acknowledge 
Vladimir Kostoglodov, UNAM and his grants, 
IN102697 (PAPIIT), 4960-T and G25842-T (CONACYT),
CONACYT grant G25842-T and our NSF grants EAR-9725712 and EAR-0125618.  
You may also acknowledge that I analyzed the data, but I do 
not require it.

Sincerely,

Notes added by Lou Estey, UNAVCO (16 Feb 2005):

First column is the solution epoch in decimal Gregorian calendar year.
The antennae positions are based on daily solutions at the nominal
given epoch (e.g. 2000.2491 is solution for no more than 24-hrs worth of
data, day 91 = March 31 of 2000).  The position deltas are site - MD01,
where a large offset has been removed from the ENV deltas.
