04 Spectra from Problem PMT Channels

We set the HV = 800 Volts for all channels which have been masked out, repaired, or otherwise had problems in 2008.  I have examined the spectra for these channels and give pdfs with each of these spectra:

I identify 37 tubes which are dead, 39 tubes which can be adjusted, and 1 with a bit problem.  We should pay careful attention to these tubes in the next iteration.
