Notes. The first column indicates the model and selection approach. The second column gives the decay time τ in Myr and its upper and lower uncertainty is the 68 % HDI. The third column shows the same for the intercept f₀ and the last column for the shift t₀. In the row of the no-shift model the shift cell is empty as this is not fitted in the model. ^aDisk selection from Luhman (2022). ^bApplied to the sources in the CCD selection.
