Westerbork (tony foley at Tue Feb 24 14:56:38 MET 1998) Minor failures

First problems; jump in formatter clock at about 1128UT (GPS-fmout changes from 2.1 to 3.1 microseconds). The telescope control computer was rebooted at about 12:17UT, so that when it restarted at 12:23UT the telescope was ~0.06 degrees offsource (telescopes try to follow using their microprocessors).

Torun (K. Borkowski at Tue Feb 24 16:17:16 MET 1998) Success

No known problems

Onsala (A. Polatidis at Thu Feb 26 13:03:33 MET 1998) Success

The inchworm motor for HEAD2 (the READ head) is not working. HEAD 1 (the WRITE head) is working properly so the data shound be OK. Please ignore the results of the readback tests in the log.
