Periodogram comparing the central wavelength ranges of Hα for HD 119850 and with and without detrending. The pEW with a width of 1.6 Å is designated by the green/dotted line for no detrending and by the red/dash-dotted line in case of detrending. The pEW of the line core is in black/solid for no detrending and in cyan/dashed for detrending. The horizontal blue lines show the FAP levels of 0.1 (dash-dotted), 0.05 (dashed), and 0.01 (solid).
