I run the code:

overlap<-kerneloverlap(xy, id, "BA", lev=70)

Sorry if that is hard to read- not sure of a better way to show it. My
questions are:

1. Why is the overlap of AGA84 with itself much less than 1?
2. Why is the overlap of MTT08 with itself more than 1?
3. Why does the overlap not change when you change the isopleth? (it
does with UDOI)

eg

> overlap<-kerneloverlap(xy, id, "BA", lev=70) overlap

Thanks for your help, and apologies I can't find a dataset to
illustrate my first problem- perhaps if I understand why it depends on
which other animals are included I will be able to identify a small
enough dataset to send you.

Thanks,
