Star formation rate (left) and molecular gas mass (right) versus core entropy for intermediate-redshift BCGs with existing CO observations from the CLASH survey and this work. The BCGs RX 1532, MACS 1447, and CHIPS 1911, which are the subject of this work, are highlighted as red circles. With blue squares, we highlight CLASH BCGs with clear CO detections from the IRAM 30m telescope (MACS 0329, Abell 1423, MACS 1206, MACS 2129, Castignani et al. 2020b) and ALMA (MACS 1932, Fogarty et al. 2019). CLASH BCGs with upper limits to their total H₂ gas mass by Castignani et al. (2020b) are reported as gray triangles. We refer to the text for further details. The vertical dashed line is located at K₀ = 30 keV cm².
