  1. The first three columns give basic information about the recording. T0, T1 and T2 are recorded on the first day at the time of onset and every hour subsequent to that. T24 is recorded on the second day at T0+24 hours.
  2. The observed values and calculated values using the three methods is given. × means, the recording was unavailable due to either recording technicians fault or fault in the hardware. The errors are highlighted.
