Notes:
A method is described to convert a two-dimensional image, which is the pattern of the scattered electrons from on target gas measured by a torodial type analyzer with a detector consists of a pair of multichannel plates and a position sensitive detector from detector's recording system, a Cartesian coordinate system, to a polar coordinate system in which physical quantities (the energy and angle of a scattered electron) are expressed. By this method, the converting coefficients are calculated with high precision and the kernel (nonzero) coefficients are stored for data conversion on disk. Since there is symmetry in the coefficients, only part of the coefficients need to be calculated and stored. A simple method for compressing the storage space of the coefficients also is described. © 1997 American Institute of Physics.
