3. NDPP Utilities

3.1. NDPP_DATA Library

NDPP is distributed with a python interface to read binary output libraries. This library provides functionality to:

1. Read in a binary library which was printed by NDPP

1. This is provided by the NDPP_lib class constructor

2. Condense the outgoing angular moments to one-group values

1. This is provided by NDPP_lib.condense_outgoing_scatt method.
2. This method has an argument of groups which is a list of groups to which are to be condensed in to one.

3. Expand the Legendre moments in to functions of angle

1. This is provided by NDPP_lib.expand_scatt

4. A method to expand the library’s distributions and report on incoming energy and outgoing group pairs who have negative probability distribution functions.

1. This is provided by NDPP_lib.test_scatt_positivity.

Examples of these methods being used can be seen in both test.py and validate_libary.py.
