==== CTF Correction in EMAN1 ====
EMAN's model was outlined in the [[http://blake.bcm.edu/dl/EMAN2/EMAN1999Ludtke.pdf|1999 paper introducing EMAN]]

This model was confirmed accurate with experimental data in the [[http://blake.bcm.edu/dl/EMAN2/GroEL2001Ludtke.pdf|2001 paper on GroEL at 11.5 A resolution]]

The derivation of EMAN's CTF correction model was in [[http://blake.bcm.edu/dl/EMAN2/CTFIEEELudtke.pdf|a rather obscure IEEE proceedings paper]]

Finally, you can the updated details from the 1999 paper in [[http://blake.bcm.tmc.edu/eman/eman1/ctfc/ctfc.html|the static EMAN1 documentation]]

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