Is there a missing k in pct_ldsino formula #2

Hello, thanks for your nice work.

I read the paper carefully and I am curious that based on the paper, the formula at line 24 in pct_ldsino.m maybe wrong. It is written as: li_hat = -log((yi-ri)./bi); while I think it should be : li_hat = -log((yi-ri)./(bi*k));

bi is the incident flux at high low, while here should be divided by the incident flux at low dose to get the transmission data.

Please correct me if I am wrong.

@oooo1114 , I'm not an author, but it seems like you're completely right
