fnirs_sync
Table with fNIRS data synchronized to a main clock with fixed frequency. The start and end timestamps of the main clock spans across all the tasks in the experiment. Each signal column is one source-detector (S#-D#) channel; `_hbo` columns are oxyhemoglobin and `_hbr` columns deoxyhemoglobin concentrations (see the documentation for the optode montage figure).
