[GRASS-user] V.kernel

I really hope I'm not exposing myself as helplessly stupid here, but: after
running a v.kernel output, what do the values of the resulting raster represent?

I would like to come up with a "hard" expression of point density - X per sq km
- for my points map, and I'm not sure whether v.kernel would do so.

The location is expressed in metres; here is the v.kernel command:

v.kernel input=radio_transmitters output=Kernel stddeviation=10000

The region resolution is set to 10000 (ie, 10 km resolution).
