Cosmic rates measured each hour when the telecope accepts cosmics which intersect the earth's surface at 330 degrees to the perpendicular.

Cosmic rates measured each hour when the telecope accepts cosmics which intersect the earth's surface perpendicularly (defined as zero degrees).

Measurements were stopped early this day because of the need to test new equipment. For all previous tests, we have been using a counter placed in the Nim bin to keep track of coincidence counts but we are now connecting the Logic Unit into the computer so that the computer will keep track of the counts. We are also working on connecting a unit that will time stamp each count.
