Notes. is the ratio derived from RPC-ICA, while ratios labelled “theo” are calculated by the forward analytical model using as input QS13 (Snodgrass et al. 2013). Qobs is calculated with the inverse model from the RPC-ICA observed ratios, with a constant velocity of 700 m s-1. Rh = heliocentric distance, (x0,y0,z0) = position of the spacecraft in CSO coordinates. The displayed time for each event corresponds to the average UT time of the whole interval.

(a)

ratio measured by RPC-ICA.

(b)

calculated by forward analytical model with Q0 = QS13 and v0 = 700 m s-1.

(c)

, forward analytical model, same as previous.

(d)

Qobs, inverse analytical model, outgassing rate calculated from RPC-ICA observations of Robs.

(e)

QS13, outgassing rate recommended by Snodgrass et al. (2013) for pre-perihelion conditions.
