sub-grid scale horizontal eddy viscosity

Hi,

The User Manual states in Table 9.2, that the sub-grid scale (SGS) horizontal eddy viscosity \nu_SGS is "-" if HLES is not used. Regarding the sub-grid scale horizontal eddy diffusivity, Table 9.3 says that D_SGS is 0 when HLES is not used. My confusion is: what happens with \nu_SGS when I do not use HLES? Does "-" in Table 9.2 mean that it is just 0?

The question might sound trivial, but it would be great to get feedback.

Best,
Sebastian
