there was an indexing error in the calculation of inelastic thermal scattering mubar in ACER for IFENG=2 ACE files. Test 74 was added to track this issue.
there was a division by zero that caused a segmentation fault in Debug mode, also for IFENG=2 ACE files.
removed an erroneously added FEND record in the PENDF file when no MF12 data gets added to the PENDF file (related to issue #250).
correction in ACER to fix issue #250. Previously it could happen that ACER picked the wrong temperature from a multi-temperature PENDF file when the materials in the PENDF only contained linearised MF3 data (no MF10, MF12 or MF23 data was added by RECONR).
fixed an indexing problem in CCCCR for delayed neutron data and added test 76.
there was a use of wrong memory addresses in CCCR not accounting for GROUPR's energy structure offset.
This update fixes a number of minor issues:
