Sensitivity (Q) coefficients for the transitions used here to constrain Δα/α in the zabs = 1.1508 absorber towards HE 0515−4414. The Q coefficients were compiled in Murphy & Berengut (2014) and are defined in Eq. (1). The lower horizontal axis shows the laboratory rest wavelengths of the transitions, while the upper axis shows the observed wavelength at zabs.
