This section about the need for a new software was removed from the "phoemplocal" documentation, and added to this post to preserve the note.

This program should serve as a clear example for developing a new program
to fit the parameter of an empirical photometric function to part of an
actual image. The differences can be summarized as follows:

1) Fit is done only once (not in a table vs. phase angle)
since the input image has a fixed geometry.
2) The data to be fit to are obtained from an ISIS cube plane
rather than modeled in in the code.
3) Similarly, the incidence, emission, and phase angles are
obtained from backplanes of the same cube and maintained
in buffers corresponding point-for-point with the image.
4) Both image data and angles should be converted to double
precision before being used.
5) Optionally, a region-of-interest mask could be obtained
from a backplane and only those pixels in the ROI used
in the fit. This would be in addition to the incidence
and emission angle tests already done in the code.

I am guessing it is related to the ISIS2 p2cd program.
