Abstract : This report discusses the THEODOLITE computer program and algorithm. THEODOLITE is a FORTRAN program designed to provide information, based upon probability theory, on the reliability of the intersection data and its corresponding estimate of bullet splashdown locations calculated by the DERANGE program. The DERANGE program takes angular THEODOLITE readings and computes estimated bullet impact points. DERANGE is useful for determining ammunition quality. The THEODOLITE algorithm is useful as are liability check of DERANGE or any program giving the same type of data as DERANGE. The THEODOLITE program works not only for the sample median estimate of impact provided by DERANGE but also for any estimate based upon the locations of the intersections generated by THEODOLITES. Several rounds must be fired in order to use this program since it relies on an approximate sample variance of THEODOLITE angles derived from all rounds fired. (AN)
