Fig. 2.
Median fractional variation of the calcium triplet 8498 Å, equivalent width as function of pulsation phase. The dashed red line marks the zero. The dotted red lines mark the average uncertainty in the mean equivalent widths used to derive the metallicity. The grey shaded regions show the phase ranges excluded from our analysis.
