Hi, Matsuura-san

I also got the same plot as Adam mentioned.

I agree with the Adam's comment. In addition, you had better check that 
dk parameter for Athena is the same as that for Artemis.

If it isn't work, why not try the latest version of Athena (0.8.059) & 
Artemis (0.8.013)? According to the header section of your attached file 
(input_data.chi), you seem to be using the older version of Athena 

best regards,

Hiroshi Oji
