DESCRIPTION:The two-point function of exactly marginal operators leads to 
 a universal contribution to the trace anomaly in even dimensions. We study
  aspects of this trace anomaly\, emphasizing its interpretation as a sigma
  model\, whose target space M is the space of conformal field theories. Wh
 en the underlying conformal field theory is supersymmetric\, this leads to
  new information about the conformal manifolds of these theories. For N = 
 (2\, 2) theories in d = 2 and N = 2 theories in d = 4 the relation between
  the sphere partition function and the Kahler potential of M follows immed
 iately.
