Translation tables for indices and symbols used in Fung et al. (2009 ▶) (Fung) and Loh & Elser (2009 ▶) (LE).

Fung	LE	Description
Indices
k	j	Indexes the set of orientations corresponding to the model diffraction patterns
d	i	Indexes the pixels in an experimental or model diffraction pattern
n	k	Indexes the set of experimental diffraction patterns
Symbols
T	K	Matrix whose entries are the pixel intensities of the experimental diffraction patterns
Y	W	Matrix whose entries are the pixel intensities of the model diffraction patterns
R	P	Matrix whose entries are the conditional probabilities of the model diffraction patterns, given the experimental diffraction patterns, e.g. Rkn is the probability of the kth model diffraction pattern, given the nth experimental diffraction pattern
