Summing up pixel values along concentric annuli

Dear All,

Is there a way to have concentric annuli of a given spacing drawn on a star
and sum up the pixel values along each annulus? I don't want the sum of
pixels enclosed by each annulus but rather the sum of pixel values along the
circumference of each. I installed the Oval_Profile.java plugin and it works
fine but I am not sure if EquiCircumference is doing what I want it to do
(even if it does, I can't specify the spacing between the annuli).

I greatly appreciate your help in advance,
Maryam
