[daip] FRING abort, 31DEC10

[Dieter Engels]

Dear Eric, we split the dataset to one time slot of about 6 minutes
of the calibrator J0121. Running FRING we get approximately the same
error messages.

The dataset J0121+1149.SPLIT and the messages FRING_error.log is on
ftp://ftp.hs.uni-hamburg.de/pub/outgoing/engels/fring_problem/

Regards, Dieter Engels
