Rotation period and spin rate vs diameter for the FOSSIL JTs (orange dots). The same is shown for previously measured JTs (green dots) and MBAs as well (the background gray dots). The green, orange, and blue dashed lines indicate rotation periods of 5, 4, and 3 hr, respectively. Note that only the objects with full and half derived rotation periods in our samples are used in this plot. All half periods are doubled for comparison to objects with full periods.
