Notes. The first segment of 12 objects corresponds to highly reliable cases. The two additional objects at the end of the table list candidate cases for which additional observations in the future will likely result in a YORP detection. The first two columns provide the number and designation of the asteroid. The third column gives the change in the secular rotation-rate ω, υ = dω/dt, which is empirically determined from the observations, and the fourth column gives the statistical significance of υ. The fifth column lists the parameter Cy introduced in Eq. (1) of Rozitis & Green (2013b; see also Rossi et al. 2009). Columns 5–8 give the rotation period P (at the epoch of detection), the size D, and the obliquity є. The last column provides the source.
