What are the coordinates of the most flat crater on Duna?

[cratercracker]

I am going to set up a base, and i want it to be in a crater (bottom is flat,a lot more science and etc.)

Can i ask you? What is the best crater on Duna?

1.It mustn't be polar atleast close to the equator.

2.Bottom must be flat

3.(insert your opinion why it is good for building bases)

4. Coordinates (if you can, if you can't,just try to describe its location)

Duna is pretty flat all around, but here is a topography map.  You can see quite a few craters and basins have flat spots on them

it doesn't really have craters in my opinion. Certainly not like the Mun does.
