Color–magnitude diagram for 616 globular clusters in the core of A1185 within the range 0.8 ≤ V − I ≤ 1.4 and I_F814W ≤ 26.5 mag. The blue and red points indicate the locations of the blue and red peaks determined by KMM fitting of the color distribution in four different luminosity bins to a model with two Gaussian components, as described in the text. Uncertainties in the peak locations were calculated via bootstrap resampling. The dashed lines denote the locations of the blue and red peaks found from KMM analysis for the entire sample of 616 clusters. A correlation between color and magnitude is apparent for the blue globular clusters (dubbed the “blue tilt”) while no such trend is seen for the red clusters.
