Nathan:

Please create a table below which records all of the 60 degree data

Then calculate the variance of the data in that table.

Measure coincidence cosmic rates at an angle of 75 degrees over the weekend.

Then during next week lets do 45 degrees overnight and continue the 0 degrees during the day.

Cosmic rates measured each hour when the telecope accepts cosmics which intersect the earth's surface at 300 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).
