Derived Barometer Elevations:
---------------------------------------------------------------
Are provided given the GPS data Kurt obtained and Unavco post
processed. The Unavco readings are adjusted by subtracting the
measured relative antenna heights that Kurt reported in his logbook
message #461.
NOTE1: the full text provided by Unavco is included at the bottom of
this message. I don't recommend reading it.
NOTE2: I don't know what the station 'PAM1-PAM1' was but i suspect
these numbers came from a short file obtained on Kurt's first
attempt which only had 11 minutes of data. The details in
the Unavco printout below indicate that PAM1-FLATLAND coincides
with the measurement times when Kurt did the 'real' survey on
the 11th, that he recorded in the log and on hand written paper.
