IVS-OHIG78 (Continuous Observations of the Rotation of the Earth and South terrestical reference frame network) 2012 Feb.29 - Mar.01 doy 060-061 Insitute for Geodesy and Geoinformtion (IGGB) of the University of Bonn, Germany Nominal Start Time: 18h00 UT Nominal End Time: 18h00 UT Duration: 24.0 hr Correlator: Bonn Participating stations: =================== FORTLEZA HARTRAO KOKEE SYOWA OHIGGINS TIGOCONC Purpose ======= The purpose of the IVS-OHIG (Southern Terrestrial Reference Frame) sessions is to tie together optimally the sites in the southern hemisphere. Because these sessions concentrate on the southern sites and do not use observing time to accurately tie these sites to far northern sites (as the Global Sessions do) they should yield a very accurate regional TRF around the South Pole. Schedule ======== This is a schedule generated with the automatic mode of sked using the variable scan length with a minimum of 60 seconds. The most recent and updated source flux models are included. SNR goals are 20/18 at X-band and 20/18 at S-band for all stations. The predicted SNRs used include a 30 ps noise contribution added in quadrature, which is a typical size for the reweight constants size for the reweight constants required in SOLVE solutions. This schedule was optimized by different features: - the covariance analysis during schedule generation considers the previous 2 hours of observations, - minor SKED optimization parameters . maximum number of observations, were optimized over the best (in a covariance sense) 75% of the possible observations, this produces a somewhat more even sky distribution, - observations were weighted by their expected SNRs, - 30 ps noise contribution added, - mimimum time between observations of the same radio source was set to 20 min - use of CvgONLY in order to improve the geometry of observation This schedule was made using 60 sources which helped improve the sky coverage. Procedures ========== Please generate the procedures for this session using drudg. Except of Syowa station who have to prepare K5 setup procedures with the existing skd file. Session Notes for session: ohig78 =========================================================== Experiment: OHIG78 Description IVS-OHIG78 Scheduler: mueskens Correlator: BONN Start: 2012-060-18:00:00 End: 2012-061-18:00:01 Current yyyyddd: 2012060 (2012.16) ( 15987 MJD, WED. 29FEB.) =========================================================== There are no observations for Kokee from 18:20 U.T. to 19:40 U.T. Kokee will participate in the intensive session during this 1.5 hour period. In addition we have several recording gaps at Ohiggins due to SAT-passes each about 18-20 minutes. =========================================================== First observations Observation listing from file ./ohig78.skd for experiment OHIG78 Source Start DURATIONS name yyddd-hhmmss Ft Hh Kk Oh Sy Tc 0537-441 12060-180000| 112 169 128 152 169| 2136+141 12060-194014| 343 343| Last observations 0208-512 12061-174540| 398 398 | 2136+141 12061-174907| 147 147 | 3C454.3 12061-175313| 73 73| 0229+131 12061-175613| 155 155 | =========================================================== Average number of obs. per baseline per source(normalized by up-time) = 3.7 Min = 0.0 Max = 55.4 (Baseline Kk-Sy on 0727-115) RMS = 8.2 Total time: 1439 minutes ( 24.0 hours).
