Water production rate measured at comet 67P/C-G
The water production rate measured at Comet 67P/C-G as a function of the comet's distance from the Sun (in astronomical units, AU). The measurements are from ROSINA-DFMS (blue diamonds); MIRO (yellow circles); VIRTIS-H (solid green triangles); VIRTIS-M (unfilled green triangles); RPC-ICA (red triangles). The dust production rate, estimated from ground-based observations, is indicated in tan crosses. The data span the period between June 2014 and May 2016. Image adapted from Hansen et al. (2016).
