Exp code	Date	Obs Time	Data Rate	Stations
U8113A	22 April 2008	12:30-14:00(UT)	256Mbps	Kashima34, Onsala60, (Tsukub32=offline)
U8113B		14:30-15:30(UT)	512Mbps

• Two sessions of e-VLBI Experiments were conducted between Kashima34-Onsala60(20m) baseline. Tsukuba32 participated observation, but correlation processing was not performed during observation. Correlation processing for Tsukuba32-Onsala60 baseline was done offline mode.
  Quick analysis in the e-VLBI experiment was performed with automatic analysis scheme (analysis core is OCCAM) developed by T.Hobiger.
• Observation schedule were made by using 'sked' program developed by NASA/GSFC with setup Min-SNR=20(X-band), 15(S-band), MAX#Obs,MinTime, MINSCAN=30sec.,
• Clock parameter for each stations (GSP-FMT=): Kashima(0.5us), Onsala(22.7us)
• 1417+385 was not detected or very low SNR. This source must be excluded in the source list, from next time.
• Session: U8113A
  • Observation has finished without any problems. Data transfer worked quite well.
  • SNRs of some scans for X-band were lass than 20, then automatic ambiguity solution scheme did not work properly. SNR preferable more than 25 from next experiment.
  • Clock parameter used for detecting fringe at the center of lag was Onsala-Kashima = -22.4 us.
• Session: U8113B
  • Observation has finished without any problems. Data transfer worked quite well, except for the first scan. Data format conversion software was run with lowest priority (nice parameter) not to disturb the data transfer by Tsunami.
  • Fringe were detected successfully for almost all scans, though quick analysis was not performed. Because clock parameter has shifted due to unknown reason, and fringe search run very slow due to large bit-rate. Fringe was found after the session.
  • Clock parameter used for detecting fringe at the center of lag was Onsala-Kashima = -30.5 us. Clock offset has increased about 8 us in case of 512Mbps mode.The reason of this must be investigated.This problem might be cause from Timing offset of Mark4/Mark5 Formatter. The Mark5 Memo document ( "047 101006 Timing Offset of the Mark 4 Formatter D.L. Smythe") describes the offset 8 us between different sampling modes.
  • Format data conversion was performed with the same PC with the data transfer to received the Onsala data. The data conversion took much time and this point must be improved by the next experiment.
