Top panel: time series of the spacecraft latitude (blue) and heliocentric distance (black). Bottom panel: time series of theestimated local outgassing rate (black) computed using a Haser model and an constant outflow velocity of 600 ms⁻¹ together with the cometocentric distance (red). COPS data was unavailable during a safe mode (2015 April 1–10); bow shock (September–October 2015) and tail (March–April 2016) excursions have been removed.
