Question GPS Primary particle source as Circle

Dear Geant Experts.
I would like to set uniform primary particle source as Circle.
I've added lines to macro file:

/gps/particle proton
/gps/pos/type Plane
/gps/pos/shape Circle
/gps/pos/rot1 1 0 0
/gps/pos/rot2 0 1 0
/gps/pos/centre 0. 0. -10.5 cm
/gps/pos/radius 5.0 cm
/gps/energy 300 MeV
/gps/direction 0 0 1


The above macro defines a planar source, circle in shape, 5 cm radius cm and centered at (0,0,-10.5) cm.
The normal of this plane is the z-axis. The energy spectrum is Mono.

Does it simulate by these commands uniform circle source according 5 cm radius?
 Results show that it doesn't have uniform distribution by radius(

Best regards, Aleksey.
