Logarithm of OH, NH, CN, C₃, and C₂ production rates of C/2012 F6 (Lemmon) as a function of the logarithm of the heliocentric distance (r). Pre-perihelion data points are represented with filled symbols and post-perihelion data points are represented with open symbols. The origin of the x-axis is perihelion. Solid lines are linear fits of the production rates variation with the pre-perihelion heliocentric distance. Dotted lines are the same for post-perihelion values.
