Distribution of all GAMA galaxies up to z = 0.355, after dust corrections as given in the text. All data and the model tracks are k-corrected to z = 0.1. The colour contours indicate the data density and the three solid lines indicate the three different evolutionary paths a galaxy would take if all star clusters within that galaxy have an IMF with a slope of α=−3 (bottom track), α=−2.35 (middle track) or α=−2 (top track). These model tracks are generated using pégase. The arrows depict the dust vectors. The red arrows represent radiative transfer model predictions calculated using the model of Popescu et al. (2000, 2011) and Tuffs et al. (2004) and from left to right correspond to τb = 8, 4, 1, all assuming a median galaxy inclination of 60° and F = 0.35. The rest of the vectors show the movement of data points for different dust extinction curves and for a BD of 4. Blue: the dust vector calculated using the Calzetti (1997) curve for the continuum corrections and Cardelli et al. (1989) curve for emission-line corrections. Green: the dust vector corresponding to corrections calculated using Fischera & Dopita (2005) curve as modified by Wijesinghe et al. (2011). Black: the dust vector corresponding to the Calzetti (2001) and Cardelli et al. (1989) curves for the continuum and emission corrections, respectively.
