The measurement data used for comparison with PTP predictions are the results of field strength surveys conducted by A. D. Ring & Associates for the Association of Maximum Service Telecasters, Inc., mostly in the years 1957-1960. These data were supplied to a panel of the Television Allocation Study Organization (TASO), and they were used in development of the TV and FM broadcast curves which appear in FCC Rules as the standard method for predicting field strength contours.
