Afρdata of comet 67P. Squares: pre-perihelion measurements on 2008 VLT images (this paper); Triangles: pre-perihelion measurements of the CARA 2008 campaign (http://cara.uai.it); Diamonds: post-perihelion measurements available in the Lowell Comet Database related to 1982 and 1983, and in the CARA Archive related to 1996. All measurements refer to the seeing-disc (upper error bar) and outermost (lower error bar) coma visible in the images. The interpolations (solid line: pre-perihelion; dashed line: post-perihelion) are the input to the dust environment model discussed in this paper.
