NJOY2016.61
This release updates the physical constant to the CODATA2018 standard. The values are those recommended in the ENDF-6 Format manual as of this writing.
Because the physical constants were updated, many of the regression tests were changed. A careful check of the differences was made before release. Please see Pull Request #140 for more details.
Note: this replaces a previous tagged version 2016.61 that had issues when running the tests. Since no actual code is changed, the original tag was removed and replaced with this one.
