solr 4.0 point type distance unit

Hi forum,

What is the default distance unit for "point" type ?

Reading solr wiki http://wiki.apache.org/solr/SpatialSearch
it implies that the distance unit is kilometers,
however based on my testing, it seems like the distance unit is in "degree"

How do I make sure if it's in "degree" or "kilometers" ?

I also posted similar question at
http://stackoverflow.com/questions/12999915/solr-4-0-default-distance-unit

Thanks

Not quite sure what you're asking here. In bold, on the page
 you mentioned is:

"NOTE: Unless otherwise specified, all units of distance are
kilometers and points are in degrees of latitude,longitude."

Asking "default distance for point type" is meaningless, it's a lat/lon
coordinate for a spot on the earth's surface. Distance _between_
two points is kilometers, as is, say, the radius with a point at its
center.

Best
