Global star formation properties of the sample. The black solid line shows the scaling relation from Renzini & Peng (2015) with 3σ scatter (shaded area). The background data (greyscale) is from the MPA-JHU catalog (Brinchmann et al. 2004), where the contours represent 2D histograms corresponding to approximately 30, 100, 300, 500, 700, 800, and 841 thousand galaxies. The purple points represent all the BASS galaxies in which the star formation rate was measured (Ichikawa et al. 2019). The red diamonds represent our sample, with BAT IDs.
