Hi,
I want to plot four circles on picture then extract mean x,y for every circle
I use this program.

;******************************************
FUNCTION CIRCLE, xcenter, ycenter, radius
points = (2 * !PI / 99.0) * FINDGEN(100)
x = xcenter + radius * COS(points )
y = ycenter + radius * SIN(points )
RETURN, TRANSPOSE([[x],[y]])
END

restore,file='sm.isv' ;/v
sm1=sm[*,*,5]
window,0,xs=999,ys=512
tvscl,sm1

n=5
for i=0,n-1 do begin
radius=10*i
pp=circle(200,352,radius)
cgPlotS, pp,color='red',thick=2.0, /Device

;*************************************

at this point no problem, I want to print mean(x,y) for every circle

how can I do it ?

help, please
