When two or more instruments are used to simultaneously measure the same phenomena, it is possible, with a few assumptions, to obtain the most efficient unbiased estimator for the precision of measurement of each instrument as well as an estimation of the true variability of the event being observed. A computer program written in FORTRAN IV which performs these calculations is presented and discussed. Up to 10 instruments taking simultaneous measurements can be handled for a series of up to 50 observations per instrument. Provision is also made to determine whether any given instrument is performing significantly different statistically from other instruments measuring simultaneously. Sample examples are also included to illustrate the programs usage and flexibility. Author
