Fraser transformation in python
Menng's matlab code fraser1.m, fraser2.m for Fraser transformation is implemented in python fraser.py (download).

Example of diffraction and transformed images:
Angles phi and beta using Kartik's code
Using Kartik's formulas for angles phi and beta kartik-2-peak-ev-angles.py.txt one can get distributions:
...
- angle phi is evaluated using two peak positions and sample-to-detector distance
- angle beta is evaluated using one !!! peak position and angle phi.
- peak and event selection need to be improved
- it could be nice to have explanation to this formalism...
Angles phi and beta from fit
Solving equation for tan(theta) we may get functional dependence between x and y peak position for angles phi and theta,
