!! @note KORC derived type containing characteristic scales used in the normalization of KORC variables. @endnote
!! These characteristic scales are problem-dependent quantities. They are calculated in [[korc_units(module)]] using the input
!! parameters of a given KORC simulation.
REAL(rp) :: time
!! @note Characteristic non-relativistic time scale given by \(1/\omega_{ce}\), where \(\omega_{ce}=e B_0/m_e\) is the
!! largest electron cyclotron frequency in the simulation. @endnote
REAL(rp) :: time_r
!! @note Characteristic relativistic time scale given by \(1/\omega_{ce}\), where \(\omega_{ce}=e B_0/\gamma m_e\) is the
!! largest relativistic electron cyclotron frequency in the simulation. @endnote
REAL(rp) :: velocity
!! Characteristic velocity. This is fixed to the speed of \(c\).
REAL(rp) :: length
!! Characteristic length scale calculated as \(c\) times the relativistic time scale.
REAL(rp) :: mass
!! Characteristic particle mass. This is equal to the electron mass \(m_e\).
REAL(rp) :: charge
