calc_cartesian_positions(d1=None, d2=None, center=True, use_cython=True)

Calculate the position of each pixel center in cartesian coordinate and in meter of a couple of coordinates. The half pixel offset is taken into account here !!! Adapted to Nexus detector definition

Parameters:

d1 (ndarray (1D or 2D)) – the Y pixel positions (slow dimension)
d2 (ndarray (1D or 2D)) – the X pixel positions (fast dimension)
center – retrieve the coordinate of the center of the pixel
use_cython – set to False to test Numpy implementation

Returns:

position in meter of the center of each pixels.

Return type:

ndarray

d1 and d2 must have the same shape, returned array will have the same shape.

calc_mask(): Returns a generic mask for Xpad detectors… discards the first line and raw form all modules: those are 2.5x bigger and often mis - behaving

calc_pixels_edges(): Calculate the position of the pixel edges, specific to the S540, d5 detector

force_pixel = True

get_pixel_corners(correct_binning=False)

Calculate the position of the corner of the pixels

Returns:: 4D array containing: pixel index (slow dimension) pixel index (fast dimension) corner index (A, B, C or D), triangles or hexagons can be handled the same way vertex position (z,y,x)

uniform_pixel = False

pyFAI.detectors.detector_factory(name, config=None)

Parameters:

name (str) – name of a detector
config (dict or JSON representation of it.) – configuration of the detector

Returns:

an instance of the right detector, set-up if possible

Return type:

pyFAI.detectors.Detector

pyFAI.detectors.load(filename)

Instantiate the detector description from a NeXus file, adapted from: http://download.nexusformat.org/sphinx/classes/base_classes/NXdetector.html

Parameters:: filename – name of the file on the disk
