Notes. The BH micro-TDE production efficiency η is defined in Eq. (3, Sect. 3.5). The low-mass group includes all clusters with MSC < 5 × 103 M⊙, while the high-mass group comprises clusters with MSC > 5 × 104 M⊙. The intermediate-mass group includes all remaining systems. The density groups correspond to the two extreme values in our sample: log ρ = 1 (low density) and log ρ = 4 (high density). The 1σ, 2σ, and 3σ intervals correspond to the ranges containing 68%, 95%, and 99.7% of the distribution, respectively. The first column reports the total number of TDE (NTDE), the second the fraction of events involving BHs and stars from primordial binaries ( fpr), and the third the cumulative simulated mass (MSC,tot). The quantities ⟨mBH⟩, ⟨m∗⟩, and ⟨qTDE⟩ denote the medians of the mass distributions of the BHs and stars involved in the micro-TDE events, and their mass ratio (m∗/mBH), respectively. Finally, ⟨tTDE⟩ indicates the median time at which the micro-TDEs occur.
