Goodness of fit plots of plane of sky (POS) velocity dispersions as a function of the projected radius for models 8 (no dark component, left), 6 (IMBH, middle) and 14 (central unresolved objects, right), which all consider two stellar populations, one of brighter (blue) stars and another of fainter (green) ones. The black curves display the maximum likelihood solutions, while the darker and lighter shaded regions show the [16, 84] and [2.5, 97.5] percentiles, respectively. The red squares show the data in logarithmic spaced bins. The vertical error bars were calculated using a bootstrap method, while the horizontal error bars considered the radial quantization noise.
