Source:

src/img/img_ctf.c

Description:

Refines the defocus with a given baseline and envelope.

Algorithm: 

	A radial power spectrum is calculated.

	A range of defocus values is tested (100-200000 angstrom, 0.01-20 um), 

	and the best fitting value accepted.

	The new parameters are written into the Bimage structure.

Arguments:

Bimage* pimage structure.
CTF* em_ctfCTF parameter structure.
float loreslow resolution limit.
float hireshigh resolution limit

Returns:

double R factor.

Prototype:

double img_ctf_refine_defocus(Bimage* p, CTF* em_ctf, float lores, float hires)
