Pressure-volume relations for the CH2 monoclinic structure. Red points and dotted line show data and fit from Fontana30; green dotted line shows values from Miyaji29; blue triangles show data from this work, with effect of temperature subtracted from the pressure; black dashed line shows best fitting EOS, and shaded region the uncertainty. The inset table shows the values used for generating the three lines with the Rose-Vinet EOS and, for our fit, associated uncertainties.
