 | MaxMovement                | RECOMMENDED. Maximum head movement (in mm) detected during the recording, as measured by the head localisation coils (e.g., 4.8)                                                                                                                                                                                                           |
 | SubjectArtefactDescription | RECOMMENDED. Freeform description of the observed subject artefact and its possible cause (e.g. "Vagus Nerve Stimulator", "non-removable implant"). If this field is set to `n/a`, it will be interpreted as absence of major source of artifacts except cardiac and blinks.                                                               |
 | AssociatedEmptyRoom        | RECOMMENDED. Relative path in BIDS folder structure to empty-room file associated with the subject’s MEG recording. The path needs to use forward slashes instead of backward slashes (e.g. `sub-emptyroom/ses-/meg/sub-emptyroom_ses-_task-noise_run-_meg.ds`).                                                                           |
-| HardwareFilters            | RECOMMENDED. [Object] of temporal hardware filters applied, or `"n/a"` if the data is not available. Each key:value pair in the JSON object is a name of the filter and an object in which its parameters are defined as key:value pairs. E.g., `{"Highpass RC filter": {"Half amplitude cutoff (Hz)": 0.0159, "Roll-off": "6dB/Octave"}}` |
