Note on mxh3

Due to performance reasons, the number of cells in the radial (comoving) distance actually used to build the skip table is always set as mxh3=int((dcmax-dcmin)/rvmax). Hence, the parameter mxh3 supplied at input will be ignored unless it is smaller than this optimum value.

Note however that mxh3 is only relevant for the performance of the algorithms. It is not related with the number of radial bins nsepv where we want to get output counts.
