FwdCoilSet serves two roles. As a template database it is the in-memory image of coil_def.dat, the canonical CTF/Elekta file mapping a numeric coil type (3022 = MEGIN VectorView magnetometer, 3024 = planar gradiometer, 5001 = CTF axial gradiometer, ...) to a normalised set of integration points and weights. As a per-channel array it holds one FwdCoil per recorded MEG channel, with the template's integration points already rotated and translated into the device-, head- or MRI-coordinate frame via the supplied FiffCoordTrans.

Mirrors fwdCoilSetRec from MNE-C; create_meg_coils() is the counterpart of read_meg_coils()/make_meg_coils() and is the only route by which raw FiffChInfo records become objects the forward solver can integrate against.
