In "IRE Standards on Television: Measurement of Luminance Signal Levels, 1958," (Standard 58 IRE 23. S1) which appeared on pages 483-486 of the February, 1958 issue of Proceedings of the IRE, the horizontal scale in Fig. 2 on page 484 was not drawn correctly below 1 mc. Going back to the primary data with that read from the published curve, corrected results are obtained. This comparison shows that errors of the order of 0.2 db can be made if the scale below 1 mc is used as a purely arbitrary scale. If the curve is read only at the marked divisions along the horizontal scale, the error is of the order of 0.1 db (or less).
