Variation in relative residuals in vbroad as a function of the catalogue V sin i (ΔV sin i = vbroad − V sin i) for different ranges of effective temperature. The x-axis V sin i scales are from the comparison catalogues. From left to right: the panels inspect fainter ranges of magnitudes, 7.5–8.5, 8.5–9.5, and 9.5–10.5 mag, except for GG (last row), where the magnitude ranges are shifted 2 mag brighter. Thick lines represent the running median on the residuals, and the coloured regions correspond to the associated 15% and 85% quantiles. Each colour corresponds to the temperature given in the plots.
