The free orbifold point of the D1-D5 CFT must be deformed with a scalarmarginal operator driving it to the region in moduli space where theholographic supergravity description of fuzzball microstates becomes available.We discuss the effects of the deformation operator on the twisted Ramond groundstates of the CFT by computing four-point functions. One can thus extract theOPEs of the deformation operator with these Ramond fields to find the conformaldimensions of intermediate non-BPS states and the relevant structure constants.We also compute the anomalous dimensions at second order in perturbationtheory, and find that individual single-cycle Ramond fields are renormalized,while the full multi-cycle ground states of the $S_N$ orbifold remain protectedat leading order in the large-$N$ expansion.
