HH gate probability integration in mod files

[brocke]

Hi,

I've noticed that sometimes the integration formula for HH gates probabilities is formulated using tau/inf variables (most of the time) and sometimes alpha/beta variables.
Do I understand it correctly, tau/inf formulation is usually used to account for the temperature?
or are there other reasons, may be numerical issues behind tau/inf choice?

thank you in advance,

Both formulations are mathematically equivalent. Which is used in any given case is entirely accidental, subject to human factors (some like one more than the other for who knows what reason, many just pick up an equation in a paper somewhere and implement code that replicates the equation).
