  A local magnetic equilibrium model is presented, with finite aspect ratio and
up-down asymmetrically shaped cross section, that depends on eight free
parameters. In contrast with other local equilibria, which provide simple
magnetic-surface parametrizations at the cost of complex poloidal-field flux
descriptions, the proposed model is intentionally built to afford analytically
tractable magnetic-field components. Therefore, it is particularly suitable for
analytical assessments of equilibrium-shaping effects on a variety of
tokamak-plasma phenomena.
