Notes. Numbers in the brackets of S_NIR are numbers of samples from the MOVIS-C catalog by Popescu et al. (2016), Q_hyd is the fraction of family members with the 0.7 μm band from previous studies (see the references under the table). The notation of “(h)” indicates presence of the 0.7-μm absorption based on the positive HYD value.
