== HMI Pipeline Module - BxByBzTransform ==

Transform disambiguated vector magnetic field from native HMI image coordinates to local planar rectilinear heliocentric coordinates.

 . Lambert's Azimuthal equivalent projection method will be used for this transformation.  This method preserves area.

 . Vector transformation will be based on formulae specified by Hagyard (1987).

 . The module can be applied appropriately only to localized ARPs.

 . Uncertainties will be estimated based on variance and covariance from the Inversion code.


===== Module Inputs =====
