Notes.

^(a)

Dust mass within the synthesized beam on 27 October.

^(b)

For a_min = 1 μm. Values obtained with a_min = 0.1 μm differ by less than 20%.

^(c)

Total dust mass in the shell produced by the outburst.

^(d)

Total scattering cross-section for a_min in the range 0.1−1 μm.

^(e)

Reduced χ² from the fit of 27 and 28 October data.
