POT3D_b

POT3D_b = Unit("POT3D_b")

Custom astropy unit for POT3D magnetic field quantities.

One POT3D_b equals 1 (dimensionless). POT3D is a potential-field solver driven by photospheric magnetogram boundary conditions; its output magnetic field is already expressed in the same physical unit as the input map (typically Gauss), so no additional conversion factor is applied.
