Tracking data from MCMU (McMurdo Bay, Antarctica) proved to be corrupt for the
analysis of day 227 (August 15). We have therefore not included data from this
site on this day. Additionally, in accordance with the advisory warning in
IGS Mail Message 320 regarding the relocation of the site's antenna, data from
PINY (Pinyon Flats, CA, USA) have been deleted for the analyses of days 230 and 231 (August 18 and 19).

WARNING: Data from MCMU have been excluded for day 227 (August 15).
WARNING: Data from PINY have been excluded for days 230 and 231 (Aug 18, 19).
