DG recommends removing reference "Table 5.2" and doc title.

4 The peak luminance as shown in the transfer function equation is 52.37 cd/m2 . The extra headroom is reserved to accommodate a range of white points including D55, D61 and D65, while still supporting the reference luminance (L) of 48 cd/m2 as specified in SMPTE ST 431-1,Table 5.2 for Digital Cinema-Screen Luminance Level, Chromaticity and Uniformity.

"... as specified in SMPTE ST 431-1. "
