Experiment Feedback

Medicina (Tugnoli Marco at Mon Sep 29 15:34:44 METDST 1997) Minor failures

All the data of the 1st tape is wrong for station problems. The data is good from the start of the 2nd tape.

Onsala (Antonis Polatidis at Tue Sep 30 11:00:56 METDST 1997) Success

Effelsberg (dgraham at Tue Sep 30 13:40:39 METDST 1997) Minor failures

tsys analysis used wrong tcal value, should be 5K not 1.4. Cable cal has peculiar behaviour.

Urumqi (Li Suqin at Tue Oct 7 04:51:09 METDST 1997) Minor failures

It is cloudy. H-maser to GPS offset is 1.93us, GPS to formator out offset is 1.81us. From 03:30:00 to 04:34:16 no observation data because the cooled receiver controller trouble. From 06:51:00 to 07:09:56 no data be recorded because the MKIII tape driver motor trouble. No other problem found. Everyscan can on source on time.

Urumqi (Li Suqin at Tue Oct 7 04:59:12 METDST 1997) Minor failures

It is cloudy. H-maser to GPS offset is 1.93us, GPS to formator out offset is 1.81us. From 03:30:00 to 04:34:16 no observation data because the cooled receiver controller trouble. From 06:51:00 to 07:09:56 no data be recorded because the MKIII tape driver motor trouble. The Cal temperature should be 10.3K not 10K. No other problem found. Everyscan can on source on time.

Effelsberg (dgraham at Mon Nov 3 14:00:49 MET 1997) Minor failures

GPS readout jumps at 1258, not known if clock really jumps or just readout

Calibration (Fredrik T Rantakyro at Wed Nov 5 16:06:27 MET 1997) Minor failures

The ANTAB formatted TSYS information can be found on VLBEER in the SEP97 directory. The file is called ea10c.antab and contains the latest antenna calibration information.

MPIfR (Walter Alef at Wed Jan 7 12:33:31 MET 1998) Minor failures

DSS65 and Crimea did not observe. First Medicina tape good except for the part when they stopped recording because they thought the procedures were wrong! Effelsberg clock jump happend towards end of observation (not in EA010D, clock staid on new value after that jump to end of session). Good data from: EFLSBERG, MEDICINA, MATERA, URUMQI,ONSALA60, NOTO, SESHAN25, WETTZELL.

MPIfR (Walter Alef at Wed Jan 14 17:15:08 MET 1998) Minor failures

Medicina lost 2 hours, Urumqi 1.5 hours.
