# pyrod
Pure python package to analyse CTR (Crystal  Truncation Rod) singal 

Overview
------------
The pyrod is a pure python package to analyse CTR (Crystal  Truncation Rod) singals
Perpare intial fitting model for phase recovery algorithm

- Convenient parameters setting 
- Organised data base of x-ray diffraction
- Expansibility
- Good fitting degree (R-square > 0.9)
- Provide initial data for further phase recovery algorithm

- Note: perovskite oxide heterojunction and superlattice structure only!
