The HSP quicklook magnetograms are reduced using a tree of Fortran codes (!) that implement the integral method:

Ronan, R. S.; Mickey, D. L.; Orrall, F. Q.: 1987, Solar Phys., 113, 353.

"The derivation of vector magnetic fields from Stokes profiles - Integral versus least squares fitting techniques"

The following code tree is available for analyzing HSP and/or IVM Stokes spectra.

Lites-Skumanich spectral inversion:

/solar/Mees/HSP/invert

The following code trees are available for analyzing HSP and/or IVM vector magnetograms.

Force-free, constant alpha field extrapolation:

/solar/Mees/HSP/bff/

Ambiguity resolution and vertical current computation:

/solar/Mees/HSP/current

The following additional documentation is available for getting started.
