This session involves five sites on the four plates. Fairbanks is on the North American Plate, Hobart is on the Australian Plate, Seshan and Urumqi are on the Eurasian Plate, and Kokee is on the Pacific Plate. Thus, this session will produce critical data for the investigation of the current crustal motions in the Asia-Pacific region combined with the data from the APSG SLR and GPS campaigns. Also, this experiment will improve the accuracy of the geocentric coordinates of the participating stations, especially Urumqi. Schedule ======== This is a new schedule generated by Guangli Wang with the automatic mode of sked. The following are the characteristics of the schedule: 1) This schedule was optimized for sky coverage. 2) Only the observations in the previous two hours of the schedule were considered for the minor options. The best 50% of the configurations were considered for minor options. 3) The "minor options" were set to select observations to maximize the total number of observations, to minimize the idle time between scans, and to minimize time between scans on the same source by thirty minutes. 5) The minimum SNR limits for all baselines were set to 20 for X-band and 15 for S-band. The schedule was made using the full sub-netting mode of sked. This resulted in fewer scans at each station but more observations because there were more scans with more stations. Correlation ========== This experiment will be correlated at the Washington Correlator with all baselines being correlated.
