The rate for the S2m L6 PMT has about twice the rate of the other
PMTs. I turned off the lights inside the shield hut, and the rate dropped
about a factor of 2, see Figure 1. I will need to search for the location
of the light leak. The rate with lights on is about 120 Hz and off is
less than 70 Hz. The corresponding right PMT does not see a light leak.
