Wb used in phased array mode.
Big problems with the Westerbork file server (RAID card and possible also disk damage); we had to replace the server on Friday evening 1st June. The file server had also given errors on Thursday.
We recorded from 15:30 to 16:44 (operator error had not enabled 2nd bank while checking the local system). Observations restarted at 20:49UT, but most of the data from 20:49 to 00:30 gave large numbers of data_check errors.
Westerbork (Tony Foley at Mon Jun 4 09:13:32 2007) Minor failures :
Single dish was used. Please change the coordinates in the vexfile accordingly.
Supplemental : Scan_check gave large errors in the restarted scan at 21:03.
scan checks from 16:44 to 21:03 are looking at the same scan.
