A Note Regarding 'Vel':
Vel is microturbulence velocity. There are currently few reliable data on its observational values. Therefore, the atmosphere model grids are computed for various values of Vel. Allowed values for this interpolation are 0.0 to 8.0 km/s. The most common value used is 2 km/s. Therefore, unless you have a specific value of Vel you would like to interpolate on, use the default value of 2.0. See Vel's influence in Fig. 5 of this paper. |
