    • -1 for the 17 to 20 June, 1 July, 18 to 23 July, 24.7 July, and 25.7 to 28.7 July periods, respectively. Rotational lines observed in the millimetric and submillimetric domains were analyzed with the excitation model of (7, 11), adopting a gas kinetic temperature of 50 K for June and of 70 K for July consistent with temperature determinations in low-activity comets. Beam offsets were taken into account in the calculations.

    • From the line intensities obtained at offset positions 10 to 15 arc sec from the nucleus on 18 to 25 July, we do not see any evidence for an extended distribution of HCN gas. Substantial departure from a nuclear source distribution is only observed on 19.6 July and is likely due to short-term variations.

    • max' and total mass at t = O. The decrease of the HCN production rate observed after 23.9 July can be fitted by indexes other than α = 3.5 but always requires that the maximum size of the debris is less than a few decimeters. Because the time sampling of our observations, the fit is not sensitive to icy grains with lifetimes smaller than one day (a < 7 cm).
