[cctbxbb] structure_factors() "d_max" equivalent

[James Stroud]

Hello All,

I'm new to cctbx and trying to get the most rudimentary understanding.

I would like to select all of the reflections within a particular resolution shell. This line from the tutorial:

  f_calc = quartz_structure.structure_factors(d_min=2).f_calc_array()

gets all structure factors through the highest resolution of d_min=2 Å (excluding 0 0 0).

My question: is there an equivalent to a d_max argument for this function (i.e. a low resolution limit)?
