Hi Seth,

Thanks. It works. I think the other possibility is to put some instruction
on the narccap website about some cleanups that are needed.

So far, I just read the x,y data so I have not found any issue. But, when
mapping the data, I found that problem. So, thank you very much for your
help.

Best,
Perdinan
