config_mp

• scan:

Mandatory, string type encapsulating scans or ranges of scans containing data for each peak. The scans/scan ranges should be arranged in ascending order.

example:

scan = "898-913,919-934,940-955,961-976"

• orientations:

Mandatory, a list of lists, each inner list defining the orientation of a peak.

example:

orientations = [[-1, -1, 1], [0, 0, 2], [1, 1, 1], [2, 0, 0]]

• hkl_in:

Mandatory, list with Miller indices representing the in-plane lattice vector.

example:

hkl_in = [3.031127677370978, 12.31353345906843, 8.75104158816168]

• hkl_out:

Mandatory, list with Miller indices representing the out-of-plane lattice vector.

example:

hkl_out = [9.77805918769193, -8.402719849515048, 8.436553021703112]

• twin_plane:

Mandatory, list with Miller indices of the twin plane. If there is not a twin plane, this should be the same as sample_axis.

example:

twin_plane = [1, -1, 1]

• sample_axis:

Mandatory, axis of the sample. The data will be rotated so that the twin plane vector in the lattice frame (hkl) corresponds to this vector in the array frame (xyz).

example:

sample_axis = [0, 1, 0]

• final_size:

Mandatory, a size in each dimension of the array holding reconstructed object.

example:

final_size = 180

• mp_max_weight:

Optional, a number between 0 and 1.0 specifying the initial coupling weight assigned to all peaks. if not provided, defaults to 1.0.

example:

mp_max_weight = 1.0

• mp_taper:

Mandatory, fraction of the total iterations at which to begin tapering the coupling weight. Coupling weight will decrease for all peaks starting at mp_taper times the total number of iterations.

example:

mp_taper = 0.6

• lattice_size:

Mandatory, lattice parameter of the reconstructing crystal. This is used to define the reciprocal lattice vectors, which are required for projecting to each peak.

example:

lattice_size = 0.4078

• switch_peak_trigger:

Mandatory, a trigger defining at which iteration to switch the peak.

example:

switch_peak_trigger = [0, 50]
