One of the spacers came out leading to the : pole slipping to one side. : BIGF time series analysis suggests that the slip on 2013-02-03 : was originally about 15 to 20mm in North and 50mm in East, : with a slight reduction after 2013-03-08 or 2013-03-09 when : the North went almost back to the way it was but there remained : a 30 to 40mm change in the East. : It is advisable to regard all ULLP data post 2013-02-02 as : suspect. : A new bracket will be made and ULLP replaced by a new station. : Station replaced by ULLO 2014-01-09 4.x Antenna Type : (A20, from rcvr_ant.tab; see instructions) Serial Number : (A*, but note the first A5 is used in SINEX) Antenna Reference Point : (BPA/BCR/XXX from "antenna.gra"; see instr.)
