It was long recognized that for para-foveal vision this function does not describe luminance perception correctly. In 1964 the CIE accepted a large field colorimetric observer, but this system had no photometric counterpart. Subsequent research has shown that y10(?) function can be used as the spectral luminous efficiency function of a 10\u00b0 photometric observer. The present report provides guidance when and how this large field photometric observer could be used, especially if luminance has to be determined para-foveally. <\/p>\n<p> Based on the detailed evaluation of the available literature data TC 1-59 came to the conclusion that the adoption of a 10\u00b0 photopic photometric observer [V10(?)] can be recommended to the CIE and that this system should be based &#8211; according to the original recommendations of the CIE Colorimetric Committee &#8211; on the y10(?) function of the CIE 1964 standard colorimetric observer. <\/p>\n<p> The report is written in English, with a short summary in French and German.
