'Fix Elekta magnetometer coil types.
Returns
raw : instance of Raw
The raw object. Operates in place.
Notes
This function changes magnetometer coil types 3022 (T1: SQ20483N) and
3023 (T2: SQ20483-A) to 3024 (T3: SQ20950N) in the channel definition
records in the info structure.
Neuromag Vectorview systems can contain magnetometers with two
different coil sizes (3022 and 3023 vs. 3024). The systems
incorporating coils of type 3024 were introduced last and are used at
the majority of MEG sites. At some sites with 3024 magnetometers,
the data files have still defined the magnetometers to be of type
3022 to ensure compatibility with older versions of Neuromag software.
In the MNE software as well as in the present version of Neuromag
software coil type 3024 is fully supported. Therefore, it is now safe
to upgrade the data files to use the true coil type.
.. note:: The effect of the difference between the coil sizes on the
current estimates computed by the MNE software is very small.
Therefore the use of mne_fix_mag_coil_types is not mandatory.'
