Subject:
TWP/MPL/C2 - Laser emission accidentally turned off
DataStreams:twpmplcbh1scottC2.c0, twpmplnor1campC2.c1, twpmplcmask1clothC2.c1, twpmplsmask1clothC2.c1,

Description:
Shortly after 00:00 GMT on 11/11/00, the MPL Energy Monitor value dropped
abruptly to zero.  At about 22:00 GMT on 11/13/00, the remote handset for
the laser diode supply was used to turn the laser back on.
