Subject: Updated site logfile for WTZZ

Attached an updated version of the station log file for WTZZ (Wettzell, 
Ashtech-Z18 receiver).

During the computations of the local site ties between WTZZ and WTZR 
(Wettzell, Rogue receiver), as well as between WTZZ and WTZT (Wettzell,
Trimble receiver) the offset between the antenna ARP and the antenna 
phase center was not taken into consideration. Therefore the values of 
the local site ties in the old station log file were not correct and 
lead to an error in the height of appr. 11 cm.

The updated log file inlcludes now the correct local site ties.
