IVS Analysis Report for RD1504 ($15JUN24XB) This report is the official IVS analysis report that corresponds to the database maintained by the IVS Data Centers for this session. (Analyzed by David Gordon, Goddard Space Flight Center. Spoolfile source: interactive solve/nuSolve analysis.) This release does not include Medicina. Medicina has not yet been correlated due to anomalous results from trial correlations that may be caused by errors in how the VDIF data are being read. Problems: HARTRAO: Missed ~3 hrs due to poor time synchronization of Mark5B. HOBART26: Mised ~4-5 hrs for 4 windstows. NYALES20: Unstable receiver LO phases in many scans caused by 5 MHz antenna cable problem over a narrow range of elevations. Rapid fringe phase variations were corrected second by second by fringing with multitone phase cal mode using only one tone per channel. TIANMA65: SR3U and SR6U deleted, MA-T6 has 20 nsec S-band ambiguities. No S-band fringes or phase cal after scan 176-0829. X-band system temperatures started rising at ~176-0720, reaching ~4x their earlier levels by 176-1200, after which they were stable. Fringe and phase cal amplitudes decreased accordingly by ~50%. MEDICINA: Not yet correlated. Recorded on Mark 5C in VDIF format. Parameterization comments: None. Other comments: None. ----------------------------------------- Session Statistics Observations: 1974 scheduled 1225 correlated (in database) 881 recoverable (usable) 852 used Session fit: 22.829 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HARTRAO 394 186 180 45.7% HOBART26 305 133 120 39.3% KOKEE 329 181 177 53.8% MATERA 605 350 337 55.7% MEDICINA 664 NOT CORR NOT CORR 0.0% NYALES20 543 345 338 62.2% TIANMA65 480 197 192 40.0% WETTZELL 628 370 360 57.3% --------------- --------- ----------- --------- ------ Station Total** 1974 881 852 43.2% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
