Denton [2020] describes some techniques using MMS magnetic field observations and current density estimates (via the curlometer technique) to perform higher order (quadratic and cubic) reconstructions of magnetic fields near reconnection areas. I imagine there might be some interest in having these available in PySPEDAS.
It seems like being able to do MDD (minimum directional derivative) calculations might be a prerequisite, in order to establish a local LMN boundary coordinate system. See https://github.com/spedas/pyspedas/issues/728
