Notes. The first column corresponds to the labeling of the curves in Fig. 1. The second indicates whether Durca (D) or only Murca (M) reactions are allowed. The third distinguishes between normal (N) and superfluid (S) neutrons. (The protons are always taken to be normal.) An X in the fourth indicates passive cooling (no heating mechanisms). An X in any of the last three columns indicates that the respective heating mechanism is present. The superfluid neutrons are always assumed to have a gap Δ_n = 1.5 MeV, and vortex creep is always assumed to have the excess angular momentum J = 3 × 10⁴³ erg s. MSPs are taken to have initial rotation periods P₀ = 1 ms, and CPs P₀ = 5 ms.
