We study the spectrum of certain two-particle operators in supergravity regime D1-D5 system, focussing on four-point correlators tensor multiplets $AdS_3\times S^3$ at tree level. In Mellin space, these are nicely determined by a single amplitude, which makes manifest large $p$ limit, connection with flat space S-matrix, and six dimensional conformal symmetry. compute $(1,1)\times \overline{(1,1)}$ superconformal blocks for two-dimensional $\mathcal{N}=(4,4)$ theory boundary, then we obtain formula anomalous dimensions exchanged symmetric anti-symmetric flavor channels. These solve an unmixing problem is analogous to one $AdS_5\times S^5$, interesting modifications. Along way show how relate those $\mathcal{N}=4$ SYM four dimensions, provide new intuition known data S^5$.
