Help on understanding clusterdump output

Hi All,
I was trying to run KMeans clustering algorithm and its been executed
successfully.
After clusterdump, I want to get a better understanding on the output:

*Key: CL-526: Value: CL-526{n=133 c=[44.729, 0.429, 0.977, 28487.102,
0.639, 0.97 0, 0.571, 0.647, 0.737, 0.383, 0.541] r=[9.890, 0.495, 1.000,
2433.780, 0.480, 1 .062, 0.495, 0.478, 0.440, 0.486, 0.498]} *

My question is, within the cluster CL-526,
does n represent the number of members in this cluster?
does c represent the center of this cluster?
if so, what does r stand for?
can anyone explain it in details?
any explanation would be appreciated.

CL-526 is the Cluster 526 and n=133 refers to the number of points 
observed by this cluster and c = [44.729 ...] refers to the center of 
Cluster as a vector and r = [9.890 ..] refers to the radius of the 
cluster as a vector.

Its explained at the bottom of this page
