NNDC cross_sections.xml error?

Hi folks,

I think I’ve found an error in the NNDC cross_sections.xml. For the following entries:

<ace_table alias=“Te-127m.71c” awr=“125.815” location=“1” metastable=“1” name=“52129.71c” path=“293.6K/Te_127m1_293.6K.ace” temperature=“2.53e-08” zaid=“52129”/>
<ace_table alias=“Te-129m.71c” awr=“127.8” location=“1” metastable=“1” name=“52129.71c” path=“293.6K/Te_129m1_293.6K.ace” temperature=“2.53e-08” zaid=“52129”/>

This causes OpenMC to crash and tell me that the name does not correspond to the names of the ACE tables, which are in MCNP form. Additionally it looks like Te-127m is the same as Te-129m.

I think it should be:
<ace_table alias=“Te-127m.71c” awr=“125.815” location=“1” metastable=“1” name=“52527.71c” path=“293.6K/Te_127m1_293.6K.ace” temperature=“2.53e-08” zaid=“52127”/>
<ace_table alias=“Te-129m.71c” awr=“127.8” location=“1” metastable=“1” name=“52529.71c” path=“293.6K/Te_129m1_293.6K.ace” temperature=“2.53e-08” zaid=“52129”/>
