Gets Y resolution to Z fit.
The X and Y resolution (mm/pixel) of an imager's pixels varies with the range. When resampling images, it is necessary to know the native resolution of each pixel. Typically, this is only needed for color/texture output. Profile cameras would have a fit set to kNULL. The fit is stored as polynomial coefficients. The Y resolution at a given Z range (mm) can be determined by:
Y resolution = coefficients[0] + coefficients[1]*Z + ... + coefficients[N]*Z^N
