This Recommendation defines a colour data representation method in order to make it possible to interchange continuous-tone colour image data over facsimile communication services such as Group 4 and Group 3 facsimile. This Corrigendum fixes errors in the description of D65 illuminant data and aligns them with ISO 13655. Variables X0, Y0and Z0are changed to "X0 =95.047; Y0 =100.000; Z0 =108.883" in the Summary, in 6.2.2.2 (White point and illuminant data) and in Appendix I ("Method for colorimetric calculation from spectral measurement"). Values of Table I.2/T.42 are replaced with correct values in ISO 13655.
