 At sea level, cosmic rays are mostly composed of MeV energy electrons and 100 MeV energy muons.  The proton flux is more than 10,000 times smaller than the electron flux.(J. Ziegle, NIM, vol 191, (1981), 419

	On October 30 and 31, we started using a new system of counting using the computer. The computer is able to collect singles data from both scintillators including coincidence. After a few trial runs, it was discovered that the scintillators were measuring completely different singles counts by about a factor of 2. In an effort to get the single counts closer, the High Voltage on the bottom scintillator was raised by 30 Volts. Now the scintillators are measuring roughly the same amount of singles but with it, the coincidence rates have increased. All the data from November 1st on will have higher rates because of this increase.		On October 30 and 31, we started using a new system of counting using the computer.
