Notes.
Production rates measured at the SMT on 7–12 May 2004 derived from an excitation and radiative transfer model assuming a pointing offset of 2′′.
A water production rate of QH2O = 2.7 × 1029 molec.s-1 was obtained from the fit to the daily averaged production rates measured by the Odin satellite (Biver et al. 2009).
Mixing ratios obtained between 20–24 May 2004 with the BIMA array and on 15 and 26 May 2004 with the 12-m ARO telescope for a parent source distribution (Friedel et al. 2005; Remijan et al. 2006; Milam et al. 2006).
