Greatest Lower Bounds on Ricci Curvature for Fano $T$-manifolds of Complexity $1$

In this short note we determine the greatest lower bounds on Ricci curvature for all Fano $T$-manifolds of complexity one, generalizing the result of Chi Li. Our method of proof is based on the work of Datar and Sz'ekelyhidi, using the description of complexity one special configurations given by Ilten and S"u\ss.
