[SLS-DC] 123B2 Corrigendum

[Kiely, Aaron B (US 332B)]

Dear Working Group,

There is a minor issue with 123B2.

The NOTE in 5.4.3.3.5.2 of 123B2 states that, “For high-entropy samples, it can be shown that k_z(t)>=2.” In fact, as the standard is written this isn’t true, it’s just extremely rare – it can only happen when bit depth is D=3. (See Annex F of the Green Book.)

We intended for the idea of this note to be normative, eliminating the need to implement a code that would be used only for a very special case. I believe we should request a corrigendum to do the following:
	1.    In 5.4.3.3.5.2, change
			k_z(t) is the largest positive integer k_z(t)<=max{D-2,2}, such that…
		to
			k_z(t) is the largest integer 2<=k_z(t)<=max{D-2,2}, such that…
	2.     Delete the NOTE in 5.4.3.3.5.2.
	3.    In 5.4.3.3.5.1.4, change
			For t>0…
		to
			For t>0 and D>3, …

Please let me know if this looks right, and if we have consensus I’ll forward this to the Editor and Area Director.

Thanks,
Aaron
