Function Documentation

img_mask_reflections()

int img_mask_reflections	(	Bimage *	p,
		Bstrucfac *	sflist,
		double	radius
	)

Masks the image using the list of reflections.

Parameters

*p	complex image.
*sflist	reflection list.
radius	radius around reflection to mask.

Returns

int error code.

mg_generate_reflections()

long mg_generate_reflections	(	Bmicrograph *	mg,
		Vector3< double >	real_size,
		double	resolution
	)

Generates reflections given the unit cell vectors.

Parameters

*mg	micrograph.
real_size	physical image size.
resolution	resolution limit.

Returns

long number of reflections generated, <0 on error.

The structure factor location is given by:
    x = uh + vk
where u and v are the unit cell vectors,
and h and k are the associated Miller indices.

mg_unitcell_vectors()

int mg_unitcell_vectors

(

Bmicrograph *

mg

)

Calculates the unit cell vectors for a 2D crystal.

Parameters

*mg	micrograph.

Returns

int 0, <0 on error.

Finds the unit cell vectors u and v by solving the equation:
    x = uh + vk
where x is the location of the reflection or structure factor,
and h and k are the associated Miller indices.
