EUROPE No.54 ( European Radio Interferometric Surveying ) 2000 FEB.07/08 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: euro54.skd LOG files name: [vlbidata.global] & vtar DAT cassette eu54li (logfile Matera) eu54ld (logfile Medicina) eu54ln (logfile Noto) eu54ln (logfile NyAles20) eu54lt (logfile Onsala60) eu54lo (logfile TIGOWTZL) eu54lw (logfile Wettzell) eu54ly (logfile Yebes) #Pfile p1560f (last #pfile) #Ffile rf1560 Nominal Start: 12:01 U.T. on Feb. 7 (day 038) Duration: 23.94 hours Nominal Stop: 11:59 U.T. on Feb. 8 (day 039) 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.

No channel discarded in final fringe. The RFI dropped down fringe amplitude at these channels more than 50% of the average value at 15 scans. MEDICINA > No particular problem was detected during correlation. NOTO > RFI at S band at channels #2 #3 (freq. 2227.99 and 2237.99 MHz) at the 17 scans at the beginning of the session. NYALES20 > No particular problem was detected during correlation. ONSALA60 > At the beginning of the session the gps-fmout was of -999986.614usec. At time 2000.038.16.20 the operator discovered and fixed it. The new gps-fmout was 13.390usec., but in the log file appeared always the old value. The log file reports "gps- fmout" and not "gps-fmout" as standard for this reason there a sign difference between the value reported in the log file and the value used in the control file for the correlation (#S file). TIGOWTZL > No particular problem was detected during correlation. WETTZELL > Stop between 038-1515 and 038-1700 due to WV00038. (Intensive). YEBES > No fringe and no phase calibration amplitude were detected at channel 8570.99 MHz during the whole session. Frequency set-up was correct, system temperature was normal, parity errors equal to other channels. No comment found in the log file. This frequency was excluded from the final fringing. REFRINGE OF DATA ---------------- All baseline with station YEBES were refringed without channels 8 (frequency 8570.99 MHz); 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): 1.1 -.1 .6 -2.6 1.0 -.3 -1.0 1.2 Parameter for the phase offset of the station Matera (S-Band): 13.6 -8.9 -4.3 -10.2 7.8 .8 Parameter for the phase offset of the station Medicina (X-Band): 2.7 -2.2 -3.8 5.7 -3.0 -2.2 1.4 .9 Parameter for the phase offset of the station Medicina (S-Band): -.2 -2.1 -.1 6.3 -1.9 -2.2 Parameter for the phase offset of the station Noto (X-Band): -1.8 -2.9 1.2 -.5 .0 21.3 -6.0 -13.7 Parameter for the phase offset of the station Noto (S-Band): .4 7.3 -6.5 -4.1 6.1 -2.1 Parameter for the phase offset of the station Nyales20 (X-Band): -1.7 -.1 3.7 -.7 -1.9 .8 .4 -.2 Parameter for the phase offset of the station Nyales20 (S-Band): .5 -5.4 4.6 2.6 1.3 -3.1 Parameter for the phase offset of the station Onsala60 (X-Band): .7 -2.1 -1.3 3.0 1.3 1.0 -.3 -1.1 Parameter for the phase offset of the station Onsala60 (S-Band): .2 1.6 -3.6 3.7 -2.1 .4 Parameter for the phase offset of the station Tigowtzl (X-Band): -.5 -3.9 -1.2 4.7 1.6 -3.8 1.6 .1 Parameter for the phase offset of the station Tigowtzl (S-Band): .7 -3.5 -1.2 3.8 -2.9 -.3 * STATISTICS ---------- ** Exp# %done COREL FRINGE hrs 1560 99.6 97.7 165.9 91.7 % QF=7-9 1.3 % QF=3-6 1.8 % QF=1-2 4.5 % QF=0 .7 % QF=A-N ARCHIVE FILES ------------- 1#AF029 2#AF030 3#AF032 4#AF034 5#AF035 6#AF036 7#AF037 8#AF038 9#AF039 10#AF040 11#AF042 12#AF043 13#AF046 14#AF049 15#AF051 16#Logs + other corr. files 17# REMARKS ====== - The DAT cassette is written in standard UNIX tar format - On the DAT cassette you will find #A-files (TAR#1-TAR#14) - TAR#15 LOG-files and other correlator files (first and second dat-cassette) - TAR#32 + All refringed data (second dat-cassette) * Data Base Vers.1 will be created by GIUB Regards Mauro Sorgente
