Gas-to-dust mass ratio of the local interstellar cloud (LIC). The filled diamond and square indicate the ratios determined by the depletion of elements in the LIC, before and after the sublimation of organic refractory material (see Appendix B). The filled circle is the gas-to-dust mass ratio of the LIC derived from the Ulysses in-situ measurements of LIC dust impacts by Krüger et al. (2015). The error bars represent the standard deviations.
