Low energy particles incident on the front detector in coincidence with the penetration of high energy particles through the side of this instrument to its rear detector may cause significant error in the fluxes recorded. In order to determine the severity of such errors, the probability of such accidentals is calculated and evaluated using the highest expected fluxes that will contribute to it. These results are then applied to data obtained from OV1-13. It is found that significant error is possible only near L = 1.4. In this region the erroneous flux recorded in any channel is never greater than the total flux recorded in the highest energy (lowest flux) channel. Subtraction of the flux (if any) recorded in this highest energy channel from that recorded in each of the other channels will produce an improved spectrum. (Author).
