4d N=2 Superconformal Field Theories typically come in families.
In the case of theories of Class-S, the "conformal manifold" is the moduli
space of complex structures of a punctured Riemann surface. All of the data
of the SCFT is fibered over the parameter space and, in the case of the
Coulomb branch geometry, it is a nontrivial fibration. This observation
has implications of both mathematical and physical interest.
