For whatever reason (forensics yet to take place) the F2 M0 BOSEM died around the power outage event last week (would be great if someone wanted to trend and append).  I'm swapping s/n 638 with 261.  261 was plugged in and reading OLV H2:SUS-ITMY_M0_OSEMINF_F2_OUTMON (in the dim room) of -6337, with H2:SUS-ITMY_M0_OSEMINF_F2_INMON reading 22899.  The dark light OLV (occulted by flag) is 31879.  OSEM input filters all enabled (nominal).  Set to 50% at 4:10 pt.
