+// Note: All the azimuth Phi angles in this and other MC classes follow
+// the convention in the Corsika program (see Corsika manual). There, phi
+// is the azimuth of the momentum vector of particles, and is measured
+// from the north direction, anticlockwise (i.e, west is phi=90 degrees).
+// When it refers to the telescope orientation, it is the azimuth of a 
+// vector along the telescope axis, going from the camera to the mirror. 
+// So, fTelescopeTheta=90, fTelescopePhi = 0 means the telescope is 
+// pointing horizontally towards South. For an explanation, see also 
+// TDAS 02-11.
