Reduced proper motion diagram for members of our sample with Gemini J-band detections (black points), L subdwarfs (green), T subdwarfs (orange), esdT candidates from Schneider et al. (2020; red; W0414 = WISEA 0414–5854, W1810 = WISEA 1810–1010), and known Y dwarfs (gray). Ross 19B and CWISEP 0156+3255 (labeled W0156) are indicated with yellow stars because they are members of our Gemini sample with J-band detections from the prior literature (Meisner et al. 2020a; Schneider et al. 2021). Some of the Y dwarfs which appear most extreme in this diagram are individually labeled: W0402 = CWISEP J040235.55−265145.4 (Meisner et al. 2020a), WD0806B = WD 0806−661B (Luhman et al. 2011), W0830 = WISEA 0830+2837 (Bardalez Gagliuffi et al. 2020), W0855 = WISE 0855−0714 (Luhman 2014b), and W1828 = WISEPA J182831.08+265037.8 (Cushing et al. 2011; Kirkpatrick et al. 2011).
