Comparison between the first and second moment velocity maps for axisymmetric Jeans modelling in the left and right column, respectively. The first two rows show the best-fit models for blue GCs, with the best fit q_DM = 1.38 in the top q_DM = 0.7 below. The bottom two rows show the residuals for the blue GCs on the top and red GCs on the bottom. The parameters used to evaluate the model were taken from Table 6 and for q_DM = 0.7 we take the other parameters at the minimal χ² based on the 2D χ² grids as shown in Fig. 9.
