Light curve, pre-whitening and pulsation characteristics for the high-f_sv star KIC005941844. Top: full light curve (left) and a small part of the light curve that indicates its multi-periodic constant-frequency nature (right). Middle: comparison of the different stop criteria used for the five pre-whitening strategies throughout the iterative pre-whitening procedure, applied to the light curve. The BIC values are relevant for strategies 3, 4, and 5, whereas the S/N value and the estimated amplitude A expressed in estimated standard deviations are relevant for strategies 1 and 2, respectively. Bottom: LS periodogram (in orange) obtained after subtracting the light curve model obtained by pre-whitening strategy 3, from the original light curve. The extracted frequencies for this model are displayed as grey lines with height equal to the extracted amplitude. We note the different y-axis scale for the inset compared to the main panel.
