nigelmegitt has just created a new issue for https://github.com/w3c/ttml2:

== Error in HLG HDR appendix step 8 ==
Step 8 of appendix Q.2 Hybrid Log-Gamma HDR currently says (third line):

> and `b = 1−4a` and `c = 0.5−a•ln(4a)`<sup>`5b`</sup>

The superscript `5b` at the end is a transcription error from BT.2100, in which the 5b is a footnote reference (in an equation!).

The line should be:

> and `b = 1−4a` and `c = 0.5−a•ln(4a)`

i.e. the superscript `5b` needs to be removed.
