That is very strange. The coordinate names shouldn't be upper case in that dataset.

Which version of Harmonica are you using?

Thank you for your reply.

1、the version of Harmonica

2、

I downloaded the data, because When I run your code , something's wrong,

 

so ,I have to download it my self, and the coordinate names are upper case(See the figure below).  Then I use the code "return pd.read_csv('aeromag.csv') " replace

the original code"return pd.read_csv(REGISTRY.fetch("britain-magnetic.csv.xz"), compression="xz")" and then modify the case of letters.
