appropriate units for mu when using range-separated functional?

I am working with the range-separated functional LC-BLYP. In the literature, many authors present the range-separation parameter mu as unitless, while a few present it in inverse bohr. The inverse distance interpretation makes more sense to me, but the NWChem documentation does not say anything about units: the documentation tells us that the default value is mu=0.33, but there are no units. Does anyone know if this is 0.33 inverse bohr? I input the coordinates of my molecule in angstroms, if that matters.

Thanks in advance for any information.

Hi Kenley,
The units are inverse bohr. mu is used in the error function which is used in the attenuation.
I'll add this to the documentation.
