I don't understand ctfestimate.py line 146 and 147. What do you mean by CTFFIND prefer the lower of the smaller of the two? I see that it is used for refining the input. Maybe you should say so in the comment. The is fine otherwise.

"I found that say you have an image with 1.1um and 1.5um defocus astigmatism. If you give CTFFIND the average value of 1.3um for the defocus and 0.4um astig (dast) then it will try to fit 1.3um and 1.8um, so you need to give it the minimum value (1.1um) for it to fit 1.1um and 1.5um."
