Scientific paper

Evaluated are four different centroiding algorithms for use in the Kitt Peak National Observatory Photon Counting Array (KPCA). Computer simulations are performed on each of the four different methods. The algorithm needs to control the placement of the center of a photon splash to 1/8±1/8 of an array element. The overall photon splash will acquire an approximate spatial area of 5×5 array elements. Restricted by the need to centroid in real-time, the algorithm must handle incoming array data at a rate of 20 MHz. Both 3×3 and 5×5 spatial algorithms are considered.
