Notes.

^(a)

Coma magnitude in the projected annulus between φ = 1′′ and φ′ = 2′′ (see text).

^(b)

Derived dust cross section.

^(c)

Derived dust mass in the coma annulus.

^(d)

Derived dust mass-loss rate for grains crossing the projected coma annulus at the reference velocity value of v = 20 m/s.
