Notes. Parameters derived from the fits of a step-like glitch model (cases F and G) and a Gaussian-like glitch model (cases H and I) to the reduced period spacings of EPIC 211779126. The results on the left side of the table show the medians and the 68 percent confidence intervals of the inferred parameters, from left to right, the asymptotic reduced period spacing, the glitch amplitude, position and width, and the phase. The right side of the table indicates the periodicity of the glitch signature and the choice of model and data.
