Sorry I am not sure what you mean. What kind of shape do you expect in the plot?

Origin of Gd data is written in README.v3.13
        source: Gd-152 from ENDF/B-VI Release 8 Tape162
        source: Gd-154 from ENDF/B-VI Release 8 Tape162
        source: Gd-156 (neutron) from ENDF/B-VI Tape 106
        source: Gd-157 (neutron) from ENDF/B-VI Tape 106
        source: Gd-158 (neutron) from ENDF/B-VI Tape 106
        source: Gd-160 (neutron) from ENDF/B-VI Tape 106

Sorry again, I cannot see the "totally different" result in the figures. Could you give me more specific part of the figure, where you felt "totally different".
