The addition of the local *τ*_{m} parameter to the set
creates a new set of models which will be labelled
.
These include models *tm*0 to *tm*9.
The local *τ*_{m} parameter is the single member of the set
and in set notation

Although the Brownian rotational diffusion parameter local *τ*_{m} is optimised, this category is residue specific.
As such the complexity of the optimisation is lower than the next two categories.
It is slightly greater than the optimisation of the set
as

dim | (15.3) |

where *k* is the number of model-free parameters.
