solarwindpy.core.units_constants

Definitions of common units and physical constants.

The values are derived from scipy.constants. All quantities stored in the Plasma object have a corresponding entry in Constants and can be converted using Units.

Classes

`Constants`(misc, kb, m_in_mp, m, m_amu, ...)	Physical constants useful for solar wind calculations.
`Units`([bfield, v, pth, temperature, n, ...])	Common unit conversion factors.
