  "NIRSCoordinateSystemDescription": "Two-dimensional local coordinates exported from the Artinis OxySoft OctaMon template. They preserve relative geometry within the headband but do not represent participant-digitized scalp locations, anatomical axes, fiducials, or 10-20 positions. z is unavailable. Group 1 (S1-S4, D1) was placed on the left frontal side and Group 2 (S5-S8, D2) on the right frontal side. template_z=0 defines only the local two-dimensional manufacturer-template plane and is not a measured anatomical depth."
