Relatively smooth data taking. At 1:40 am, noticed that Viprobe program was
dead because the connection to sensors was lost. (The program is used to
monitor and tune the RF transition unit of ABS.) Called Genya; but the problem
couldn't be fixed then. So need to monitor ligit -- if RF is off, as suggested by
Genya, ligit should drop to 1~2E-8 torr.

Blast power supply tripped once; HV IOC got a broken pipe once; coda died
twice.

Another problem is related to the auto-cruncher. Since it hung once and it was not noticed in time, a good run, 10023, was not caught up by the cruncher,
and elog didn't make an entry for it. The run has been crunched manually, but
the elog entry is sitll missing.

Runlist was updated. Good runs: 10013, 10015-10020, 10022-10025.

pol.log has been updated. The pol results for yesterday's C shift:
 runs: 10003-10005, 10007-10012
 Vec_L: 0.747 +/- 0.071
 Vec_R: 0.434 +/- 0.062
 Pzz from L/R diff: 0.837 +/- 0.188
 charge: 1.37 kC
