The corrected single-excitation calibration

The recovery formula agrees with the supplied Hawk02-B calibration CheungHawk02B. Erasing the emission-time label gives a coarse snapshot record with entropy $h_2(q_n)+(1-q_n)H(u)$, but does not change the recovery optimum: time can be resampled with input-independent conditional probabilities $p_j/(1-q_n)$. The refined and coarse records have different entropy ledgers.

For a pure unreferenced input the coherent entropy is $h_2(q)$, bounded by one bit regardless of the number of cells. Taking ${\theta }_1=\pi /4$, ${\theta }_2=\pi /2$ gives coherent entropies $(0,1,0)$ for a basis input and cumulative classical entropies $(0,1,1)$. Other prepared turnover sequences, including the supplied En02-D example, are comparisons rather than premises of the Haar Page derivation CheungEn02D.
