This cable is guaranteed to behave well at temperatures to -60 C occurring in winter. An additional Ashtech Z-12 receiver was collecting the data from the second antenna set up 30 meters away from the antenna of YAKZ. Such data were collected for 2 days before and for 2 days after the cable change. This allowed us to detect if there was any apparent "change" in the position of YAKZ resulting from the change of the antenna cable. We will report the result as soon as the data are processed. At the same time, the MET3 meteo package was set up at YAKZ. RE: BILI The data from BILI are made available at world data centers about one day later as compared with other stations operated by RDAAC/Lamont-Doherty (YAKZ, MAG0, PETP, ARTU, YSSK, TIXI). This happens because the data from BILI are transferred by direct computer-to-computer link to MAG0 via the dialup telephone line. We expect the acceleration in the data transfer from BILI after the internet satellite link is installed there. RE: YSSK After 18-OCT-99 (doy: 291), the files for three dates are incomplete or missing at YSSK. We are working on the reason with the operator at YSSK.
