Title: Equally spaced 9 step grey scales according to TUBLOG,Ua for four display reflections
Yref=4, 2, 1, (100 or 110 or 120 or 200 or 60) on ten pages
1. Introduction and goals.
2. Five lightness and tristimulus value ranges between black N and white W.
3. delta L*N to L*W: -50_50, -52,8_53, -55,6_55,7, -71,4_71,5, -34,0_34,1.
4. delta YN to YW: 4_100, 3,6_110, 3,3_120, 2_200, 6,7_60.
5. Contrast YW:YN: 25:1, 30:1, 36:1, 100:1, 9:1.
6. with regularity index g* according to ISO/IEC 15775:2022, annex G.
7. Discussion of gamma values for different ranges.

The following ten pages ied0 to ied9 of this chapter
show the content with links to the single figures in up to six formats.
