Description

Complete set of analysis summary plots for 72 RR Lyrae variable with detected mean-magnitude variations, performed with a modified Fourier-fitting method, as described in the article "RR Lyrae stars with variable mean magnitudes " (Hajdu et al. 2026, A&A).

Each page contains the analysis summary of one star. Panel a: the original OGLE I-band light curve folded with the period of pulsation, with the corresponding Fourier fit overlaid. Panel b: same as (a), but with the long-term changes removed. Panel c: same as (a), but for the V-band data. Panel d: same as (b), but for the V-band data. Panel e: the I-band data after the subtraction of the Fourier light-curve model. The orange dots and lines show the fit of the long-term brightness changes. Panel f: same as (e), but for the V-band light curve. All light-curve points are colored according to the estimated mean-magnitude values at the times of the observations, with lighter and darker points corresponding to brighter and fainter epochs, respectively. Above the panels, the OGLE ID, the pulsation period, the amplitude (∆IDR (I)) and the amplitude ratio (r_{I,V} = A(I)/A(V)) of the mean-magnitude changes are given.
