Files listed below are available in Unix compressed format and can be retrieved using anonymous ftp to sideshow.jpl.nasa.gov (128.149.70.41), directory pub/jpligsac/0748.

Also, the inclusion of RCM5 caused an excessive number of outliers in our solutions for days 131 and 132 (May 11,12). We have excluded these sites from our analyses on the corresponding days. We continue to exclude data from WEST; see IGS Mail Message 585 for details. Also, according to IGS Mail Message 597, the receiver at VNDP was replaced on day 133 (May 13). Data from this site was not available for this or subsequent days of this week at the time of processing. As noted in several of our recent analysis reports, it has been necessary to exclude NLIB on numerous days of processing. We understand that poor performance at this site is possibly being caused by a faulty receiver cable. We have chosen to delete data from NLIB indefinitely, pending further notice that the data from this site are consistently usable. WARNING: Data from NLIB and WEST excluded for the entire GPS week 748. WARNING: Data from BRMU excluded days 129 and 130 (May 9, 10). WARNING: Data from RCM5 excluded days 131 and 132 (May 11, 12). WARNING: No data from VNDP days 133 and 134 (May 13, 14).
