EMAN Wiki

EMAN's model was outlined in the 1999 paper introducing EMAN

This model was confirmed accurate with experimental data in the 2001 paper on GroEL at 11.5 A resolution

The derivation of EMAN's CTF correction model was in a rather obscure IEEE proceedings paper

Finally, you can the updated details from the 1999 paper in the static EMAN1 documentation

EMAN2 is going to use a new model for easier CTF correction…
