In the 2019 May 5 XMM-Newton exposure of 1ES 1927+654 the preferred X-ray covariance changes from Matérn-3/2-like to DRW-like, sharply at ~23.5 ks in the hard band, after corona reappearance but before later hardening.

Gaussian-process evidence for a stochastic-variability transition in the recovering corona of 1ES 1927+654
