DESCRIPTION:The pair distribution function g(r) plays a central role in li
 quid state theory\, linking structure and thermodynamics. It is typically 
 measured by constructing a histogram of the distances between all pairs of
  particles\, which is used in simulations and experiments where single par
 ticle coordinates can be obtained. Here\, we present a novel method based 
 on Henderson&rsquo\;s method [1] for measuring the cavity distribution fun
 ction\, going beyond our recent work on particles with hard interactions [
 2]. The method measures g(r) in a highly efficient way\; moreover\, it all
 ows us to obtain an effective pair potential between colloidal particles i
 n experiment.
