Detailed Description of the Data Product
_________________________________________
.. DetailedDescStart

This output product is the 2D Cartesian and Projected two-point
cross-correlation function at different separation scales.  The
product contains 3 FITS files: one for the 2D pair counts, one for the
2D Cartesian two-point cross-correlation function and one for the
projected two-point cross-correlation function.

.. note::
  In the 2D Cartesian product, the separation bins in the first dimension are the
  components along the perpendicular direction to the line of sight while the
  separation bins in the second dimension are the components along the parallel
  direction to the line of sight.
