Dust production rates derived from the PACS 70 μm (blue curve) and 160 μm (red curve) maps of comet C/2012 S1 (ISON) obtained on March 13 2013 UT. The black curves show values derived from Afρ = 900 cm. Plain lines are for amin = 0.1 μm. Dashed lines are for amin = 1 μm. Refractive indices of olivine are used and we assumed QCO = 4 × 1027 molecules s-1.
