EUROPE No.55 ( European Radio Interferometric Surveying ) 2000 MAR.16/17 Final Correlator Notes B o n n C o r r e l a t o r [ Geodetic Institute of University of Bonn ] Schedule name: euro55.skd LOG files name: [vlbidata.global] & vtar DAT cassette eu55li (logfile Matera) eu55ld (logfile Medicina) eu55ln (logfile NyAles20) eu55lt (logfile Onsala60) eu55lw (logfile Wettzell) eu55ly (logfile Yebes) #Pfile p1561f (last #pfile) #Ffile rf1561 Nominal Start: 12:01 U.T. on Mar.16 (day 077) Duration: 23.94 hours Nominal Stop: 11:59 U.T. on Mar.17 (day 078) Correlator: Bonn CORRELATION =========== Wettzell was the clock reference station for correlation. This experiment was correlated at the Bonn Correlator in three passes. Several scans have been re-correlated.

STATION COMMENTS ---------------- CRIMEA > The operator reported that station was not able to observe due to lack of power electricity MATERA > RFI dropped down fringe amplitude at these channels more than 50% of the average value at 13 scans. MEDICINA > The parity error rate was 10^-2/10^-3 at reverse passes on tracks 26 and 28. All data were refringed with an higher maximum allowable fraction of bytes in error (0.5 instead of 0.01). NYALES20 > No particular problem was detected during correlation. ONSALA60 > No particular problem was detected during correlation. WETTZELL > Stop between 076-1630 and 038-1830 due to WV00076. (Intensive). YEBES > The station could observe only nine hours. The operator had to stop the observations due to failure of two antennas' motor. No fringe was found also during the nine hours of observing time. All data were not correlated. REFRINGE OF DATA ---------------- All data with station MEDICINA were refringed with higher maximum allowable fraction of bytes in error (0.5 instead of 0.01); NOTE: In the final fringe was used Wettzell as reference station and all the the average phase offset for each channel and for each station was corrected with the following values: Parameter for the phase offset of the station Matera (X-Band): -1.3 2.9 -1.7 -.3 .6 -2.4 2.7 -.6 Parameter for the phase offset of the station Matera (S-Band): 14.6 -7.8 -4.0 -11.6 8.6 1.2 Parameter for the phase offset of the station Medicina (X-Band): 1.3 .4 -3.0 4.1 -3.8 -4.0 3.2 1.5 Parameter for the phase offset of the station Medicina (S-Band): -1.3 -1.4 .4 6.5 -1.0 -3.6 Parameter for the phase offset of the station Nyales20 (X-Band): -3.3 1.2 2.6 1.8 -1.9 -.6 1.2 -.6 Parameter for the phase offset of the station Nyales20 (S-Band): -1.3 -1.7 4.8 2.5 3.5 -1.7 Parameter for the phase offset of the station Onsala60 (X-Band): -3.8 -.2 -1.3 6.2 1.2 .2 .6 -3.0 Parameter for the phase offset of the station Onsala60 (S-Band): .2 1.5 -4.1 4.1 -2.7 .2 * STATISTICS ---------- ** Exp# %done COREL FRINGE hrs 1561 100.0 42.0 46.2 93.4 % QF=7-9 2.8 % QF=3-6 1.8 % QF=1-2 .7 % QF=0 1.1 % QF=A-N ARCHIVE FILES ------------- 1#AF064 2#AF065 3#AF066 4#AF067 5#AF068 6#AF079 7#Logs + other corr. files 8# REMARKS ====== - The DAT cassette is written in standard UNIX tar format - On the DAT cassette you will find #A-files (TAR#1-TAR#6) - TAR#7 LOG-files and other correlator files (first and second dat-cassette) - TAR#9 + All refringed data (second dat-cassette) * Data Base Vers.1 will be created by GIUB Regards Mauro Sorgente
