5 15:18 pwrOfChan[2] — tells you what exponent was applied to
corresponding channel data to create this trace. (For
example, pwrOfChan[0] is the exponent applied to
the_CHANNEL record[0]’s data.)
record [0] for row channel
Chan [0] “ ”
record [1] for column channel
Chan [1] “”
NOTE: You must divide each pwrOfChan value by 48 to obtain
the true value of the exponent.
