This has now been rectified and copy of the complete log follows. You should also note that the data files stjo0571.95o and stjo0571.95n originally submitted CDDIS and corresponding to the first 12 hour of day 057 (prior equipment and height changes) contained the wrong header information. These two files have been re-transmitted to CDDIS with the correct (prior change) header information today 28-feb-95 at12:15 UT. We apologize for this confusion. -- Robert Duval Geodetic Survey Division Tel: (613) 947-2786 Natural Resources Canada (NRCan) Fax: (613) 995-3215 615 Booth Street E-mail: duval@geod.emr.ca Ottawa, Ontario K1A 0E9 ***************************************************************************** ***************************************** ST JOHN'S (STJO) SITE INFORMATION ***************************************** 0.
