Astro Mat Lab methane-ethane solidus data

Data points for methane-ethane solidus collected at the Astrophysical Materials Lab at Northern Arizona University.<br>Lower and upper diode values are the average of the temperatures for each spectrum taken in a cell scan and then an average of those values before and after crossing the solidus boundary<br>Temperature calibration for solidus data was obtained using experimental values from literature of the freezing point of methane, the point of nitrogen, and the alpha-beta transition of nitrogen. For the freezing points, we decreased the temperature of the lower diode by increments of 0.01 until ice was visibly apparent. Since the alpha-beta transition is not visible, we identified it by the Raman shift in the nitrogen peak. Overall, the correction is small and approximately linear.
