  We develop criteria sufficient to enable detection of macroscopic coherence
where there are not just two macroscopically distinct outcomes for a pointer
measurement, but rather a spread of outcomes over a macroscopic range. The
criteria provide a means to distinguish a macroscopic quantum description from
a microscopic one based on mixtures of microscopic superpositions of
pointer-measurement eigenstates. The criteria are applied to Gaussian-squeezed
and spin-entangled states.
