  We present CLEDB, a "single point inversion" algorithm for inferring magnetic
parameters using I,Q,U, and V Stokes parameters of forbidden magnetic dipole
lines formed in the solar corona. We select lines of interest and construct
databases of Stokes parameters for combinations of plasma thermal and magnetic
configurations. The size and complexity of such databases are drastically
reduced by taking advantage of symmetries. Using wavelength-integrated line
profiles, each of which might be decomposed beforehand into several
line-of-sight components, we search for nearest matches to observed Stokes
parameters computed for the elongation corresponding to the observed region.
The method is intended to be applied to two or more lines observed
simultaneously. The solutions initially yield magnetic orientation, thermal
properties, and the spatial position of the emitting plasma in three
dimensions. Multiple possible solutions for each observation are returned,
including irreducible degeneracies, where usually sets of two solutions are
compatible with the two input I,Q,U, and V measurements. In solving for the
scattering geometry, this method avoids an additional degeneracy pointed out by
Dima & Schad (2020). The magnetic field strength is separately derived from the
simple ratio of observed to database Stokes V data, after the thermal
properties and scattering geometry solutions have been determined.
