The change can be summarized as * data collected until JDAY 285 (12/10/1998) with ASHTECH GG24 receiver with serial no.120, * no data collected on JDAY 286 (13/10/1998) and JDAY 287 (14/10/1998), * data collected since JDAY 288 (15/10/1998) with ASHTECH GG24 receiver with serial no.163. The problems with the receiver concerned the logging of raw data messages, and resulted in complete epochs of data missing from the RINEX observations files. The number of missing epochs was however relatively small, usually only a few epochs per day, and the data of the other epochs are not though to be affected by this or any other problem.
