Pot3dQuantities

Literal type alias for the 3 POT3D magnetic field output quantities.

POT3D is a potential-field solver that outputs only the three spherical components of the magnetic field: 'br' (radial), 'bt' (co-latitude), and 'bp' (longitude).

Note

POT3D mesh codes are the bitwise complement of the corresponding MAS magnetic field codes: POT3D_mesh = 0b111 ^ MAS_mesh. Where MAS places each component on the face through which it is the outward normal (face-centred), POT3D places the same component on the opposite pair of edges (edge-centred).

Warning

POT3D output files carry no intrinsic physical unit. The values are stored as dimensionless quantities (unit POT3D_b = 1) whose physical interpretation depends entirely on the unit of the photospheric boundary magnetogram used to drive the simulation — typically Gauss, but this is not guaranteed. Always supply the correct unit explicitly via the unit keyword argument of PsiData(); calling read(unit='physical') on a reader opened without a unit override will not perform a meaningful conversion.
