This is a highly simplified synthetic diagnostic which
calculates the cross phase between the electron density and the
perpendicular electron temperature for comparisons with DIII-D.
Returns the value of the cross-phase at the outboard midplane and
integrated over all v and x. We can generalize this routine to
other fields at some point, but for now this is just a skeleton for
a more realistic synthetic diagnostic.
