Description

The Lorentz correction factors $d$-dependent and/or $\theta$-dependent contributions into the data. The currently implementation does not include error bars, i.e., we assume it is exact. There is however significant and somewhat know uncertainty. For example, the error bars on $\theta$ are given (amongst other things) by the pixel/voxel size and the sample size. I think we should include this when such information is readily available.

Research direction

Start by locating the implementation of the Lorentz correction factors and reviewing how d, theta, pixel or voxel size, and sample size are represented in the data. Define how uncertainty should be propagated and when information is available; done means the correction includes error bars without assuming the inputs are exact.
