Question about the input parameter yaw_angles_baseline

[Edward-Ernest]

Hello everyone,
I am new to use Floris to do some research about wake and wind farm. Recently, I did some try with the optimization tools, but I can't understand the meanings of the input parameter yaw_angles_baseline. I know that yaw_angles_baseline is used to calculate the initial and baseline power production. But will it have influence to the output yaw angles optimized? For example, if I set yaw_angles_baseline as 50 deg and wind_directions as 260 deg for one-turbine wind farm model, which one of these two angles will be relative to the optimized yaw angles?

So yaw_angles_baseline is just used to calculate the baseline power. The yaw angles are specified relative to the wind direction. Having a wind direction as 260 and yaw angle of 0 would mean the nacelle heading is 260 deg. So that is why the default assumption is that the yaw angles are 0 for all turbines and all directions, which approximates normal operation.
