Marginalized joint 68% and 95% CL for (ns,dns/ dlnk) using Planck TT+lowP and Planck TT, TE, EE+lowP. Constraints from the Planck 2013 data release are also shown for comparison. For comparison, the thin black stripe shows the prediction for single-field monomial chaotic inflationary models with 50 <N∗< 60.
