Library Reference - Phasing Operations

Save Sequence

Save sequence data to a NumPy file.

Parameters:

Output file

User provided path string for the output NumPy file.

Save Support

Save Support data to a NumPy file.

Parameters:

Output file

User provided path string for the output NumPy file.

Save Residual

Save Residual data to a NumPy file.

Parameters:

Output file

User provided path string for the output CSV file.

Save PSF

Saves the internally stored Point Spread Function data to a NumPy file.

Parameters:

Output file

User provided path string for the ouput NumPy file.

Co-ordinate Transformation

Perform a co-ordinate transformation on either sequence data or an input array. The transformation is derived using the principles as demonstrated by Pfeifer, M.A. . The generated co-ordinate array is stored internally and is accessible for viewing with the memory array keyword memorycoords.

Parameters:

Transform from

Source from which to perform the transformation against.

Transform type

Transform in real or reciprocal space.

Input data

User provided path string to the input NumPy file.

Output amp file

User provided path string for the output amplitude VTK file.

Output phase file

User provided path string for the output phase VTK file.

Rocking curve type

Theta (\theta) or Phi (\phi) rocking curve measurement.

Array binning

Amount by which the array was binned. See the section on binning for further details.

2theta

2 \theta angle.

d theta

Increment angle for \theta rocking curve measurement.

phi

\phi angle.

d phi

Increment angle for \phi rocking curve measurement.

Pixel {x,y} (microns)

Detector pixel dimensions, in microns.

wavelength (nm)

Wavelength of light used in experiment. Units of nanometres.

Arm length (m)

Distance from the sample to the centre of diffraction pattern at the detector. Units of metres.

CCD x-axis flip

Reverse the direction of detector x-axis readout. Required for some PI CCD detectors.

Experimental geometry:


Image

Curved arrows show the direction of rotation of object (as opposed to the axis). The beam is assumed to travel along the positive x direction.

Save Co-ordinates

Save Co-ordinates data to a NumPy file.

Output file

User provided path string for the output NumPy file.

Note

A co-ordinate transformation must occur prior to this operation.
