Activity indicators time series derived before the YARARA correction. Panel (a): FWHM time series. It is possible to see trends in the different datasets. For H03 we have a trend with the change of focus of the instrument, while for H15 and E19 we have a linear correlation with the temperature of the echelle gratings. Panel (b): GLS periodogram for FWHM. Panel (c): BIS time series. It is possible to see a linear trend in E19 and H15. Panel (d): GLS periodogram for BIS. Panel (e): Time series of Contrast. Panel (f): GLS periodogram of Contrast. Panel (g): Hα time series. Panel (h): GLS periodogram of Hα. Panel (i): S-index time series. Panel (j): GLS periodogram of S-index. Panel (k): Na I D time series. Panel (l): GLS periodogram of Na I D. The red/green/blue horizontal dashed lines indicate FIP levels of 10/1/0.1 % respectively.
