How is Ligand Efficiency calculated?

The ligand efficiency parameters are described in Table 5.3 in the Glide User Manual:

ligand efficiency: GlideScore / (number of heavy atoms)
ligand efficiency sa: GlideScore/ (number of heavy atoms)2/3. This efficiency metric approximates the effect of surface area.
ligand efficiency ln: GlideScore/(1 + ln(number of heavy atoms))
