Detailed Description

Program to create interpolation tables of the PDF of the arrival time of the Cherenkov light from a bright point.

The PDFs are tabulated as a function of (D, cos(theta), t), where:

  • D is the distance between the bright point and the PMT;
  • cos(theta) the cosine of the PMT angle;
  • t the arrival time of the light with respect to the Cherenkov hypothesis.

The orientation of the PMT is defined in the coordinate system in which the position of the bright point and that of the PMT are along the x-axis and the PMT is oriented in the x-y plane.
