Evolution of the Hα line luminosity as a function of time (left panel), R_BB (middle panel) and T_BB (right panel). The plot is color-coded as follows: The H+He Iron-rich (with potentially O III lines) events are plotted with cyan, the H+He Nitrogen Bowen events are plotted with blue, the double-peaked H events are plotted with red and the plain H events are plotted in orange. AT2017eqx does not meet the criteria of any of these four subcategories and is plotted in gray. The last two H subcategories show very high Hα luminosity compared to the rest as well as low blackbody temperatures. This subcategory grouping is summarized in Table 5.
