Re: [Matplotlib-users] Basemap: What is the angular domain for coordinates?

[reckoner <rec...@gm...>]

Thanks for your reply.

       >>> m = Basemap(resolution='c',projection='robin', lon_0=-120.)

doesn't have lonmin, lonmax variables. However, when I do

       >>> m(*m(190,0),inverse=1)
(-169.99999999999997, 0.0)

Which implies that the angular domain for longitude is [-180.,180], right?

Thanks!
