Notes. Results for dust particles made of a matrix of amorphous carbon with inclusions of crystalline ice, with an ice content of 45% in mass. Column (1): range of dust production rates inferred from the flux density at 70 μm for a_min = 0.5 to 10 μm, size index α from −4.5 to −2.5, and a_max = 250 μm. Column (2): same as (1), but for a_min and α values providing a 70 μm to 160 μm flux density ratio F₇₀/F₁₆₀ consistent with the observations. Column (3): same as (1), but for a_min and α values providing a 16 μm to 24 μm flux density ratio F₁₆/F₂₄ consistent with the Spitzer observations undertaken on 23–24 November 2003 (Schambeau et al. 2021).
