application definition, extends NXobject
This is the application definition for x-ray or neutron tomography raw data with phase contrast variation at each point.
In tomography first some dark field images are measured, some bright field images and, of course the sample. In order to properly sort the order of the images taken, a sequence number is stored with each image.
These symbols will be used below to coordinate datasets with the same shape.
nBrightFrames: Number of bright frames
nDarkFrames: Number of dark frames
nSampleFrames: Number of image (sample) frames
nPhase: Number of phase settings
xSize: Number of pixels in X direction
ySize: Number of pixels in Y direction
