    • note
    • More rigorously, the proportionality coefficient must be very small if it exists, less (in absolute value) than 15 kg m V at 55.6 C and less than -15 kg m V at 59.6 C. These upper limits were deduced from the analysis of the noise in the measurements of I1 below the onset of instability.
