What is the formula for function "Mean"

[Harper19]

Appreciate the development of this great tool. For the function Mean, I am a little bit confused about the formula.
I would assume it is mainly based on total mapped bases/genome length. Is it correct? Or the denominator would be the covered bases only and the not covered region will not be take into calculation?

Thanks!

Thanks for kind words.

It's the whole genome size, assuming you are working in genome mode.

There's an example in the readme which might help too.
