JADE-1211 (Japanese Dynamic Earth observation by VLBI) 2012 Nov 15-16 Notes prepared by YM Geographical Survey Institute, Japan Session JD1211 Start 2012-302 02:00:00 Nov 15 End 2012-303 01:57:19 Nov 16 Stations Duration: 24 hours Correlator: TSUKUBA(GSI) PURPOSE ======= The purpose of the JADE sessions is to monitor the plate motion and the local crustal movement around Japan. In 2012 fiscal year, JADE session will be carried out once a month. NETWORK ======= The standard configuration of the JADE projests consists of some stations. Code : Station SCHEDULE ======== This schedule was made by YM using sked. Schedule setup parameters: Early start sec Corr. tape sync time ON sec Minimum scan length sec Maximum scan length sec Minimum SNR by baseline for multi-baseline scans X-band (margin 3) S-band (margin 0) Ts Ts S3 20 S3 15 Automatic scheduling setup: optimize for uniform sky coverage at all stations, maximize the number of observations, minimize slewing time, minimize time between scans, consider the top 0 of ranked scans for selection, consider the last 0 hour of scans for sky coverage calculations, minimum : min between scans on the same source. The characteristics of the generated schedule are listed below. These will vary slightly for each schedule that is generated. Schedule characteristics: Average scan length seconds Median SNR 25 at X-band 25 at S-band Number of observations 239 observations Average scans per station scans FREQUENCY SEQUENCE ================== Chann# Band Skyfreq(MHz) LOfreq(MHz) 1 x 8204.99 7680.0 2 x 8214.99 7680.0 3 x 8244.99 7680.0 4 x 8304.99 7680.0 5 x 8414.99 7680.0 6 x 8494.99 7680.0 7 x 8544.99 7680.0 8 x 8564.99 7680.0 9 s 2232.99 1600.0 10 s 2240.99 1600.0 11 s 2256.99 1600.0 12 s 2312.99 1600.0 13 s 2344.99 1600.0 14 s 2352.99 1600.0 APPENDIX ======== SKED Summary from file /opt/sked/skd_files/jd1211.skd for experiment JD1211 (all scans with at least one subnet station) Average number of obs. per baseline per source(normalized by up-time) = 4.8 Min = 0.0 Max = 29.8 (Baseline Ts-S3 on 1921-293) RMS = 8.8 Total time: 1434 minutes ( 23.9 hours).
