What are the optimal ctftilt parameters?

Hello Niko,

Are the parameters written in ctftilt.com the optimum ones? And is there different optimums for, lets say film at 60 000x and 4k ccd at 100 000x? Or is it actually not so useful for a ccd data collection where the recorded area is much smaller?
in particular, I am not sure what TiltA and TiltR are.

By advance, thank you.

original parameters:
128,200.0,8.0,5000.0,30000.0,1000.0,0.0,2.5
!Box,ResMin[A],ResMax[A],dFMin[A],dFMax[A],FStep[A],TiltA[deg],TiltR[deg]

Parameters that I've put in today for film data at 60 000x. :
128,50.0,8.0,5000.0,50000.0,100.0,0.0,2.5
!Box,ResMin[A],ResMax[A],dFMin[A],dFMax[A],FStep[A],TiltA[deg],TiltR[deg]
