Numerical model of nuclear spin decoherence for a homogeneous ensemble of $N = 12$ spins: normalized echo amplitude against free evolution time $T_{\mathrm{FreeEvol}}$ under a Hahn echo and $n_{\mathrm{Cycles}} = 1$, 12, 32 and 48 cycles of CHASE-40 decoupling, $T_{\mathrm{Rf}} = 20\,\mu$s. Time is in seconds, where the print uses ms.
