Model-fitted count spectra of 4FGL J0136.5+3906 over 17 yr (left) and 11 yr (right) subset with “N” logarithmically spaced energy bins. Black dots and black line: data and total model; light gray lines: background sources; red dotted–dashed line: source model; blue solid line: log-parabola continuum; red dashed line: Gaussian excess. The corresponding spectral-fit parameters are listed in Table A1. Partial spectra are presented herein to provide a visual guide.
