Change size of spherical mask in heterogeneous refinement


In heterogeneous refinement, it seems that a soft spherical mask is applied at each iteration (as the volumes appear to be spherically windowed even if real space windowing of particles is turned off).

Would it be possible to make this user adjustable in the same way as it is during 2D classification? There are cases (e.g. large particles in tight boxes, or small particles at high defocus) where it would be convenient to be able to alter this.
