Comparison of derived spectroscopic distances and distances based on Gaia EDR3 parallaxes (upper panel), and their relative differences (lower panel). Diamonds represent the objects analysed in this work, while dots correspond to those of Paper I – filled symbols are used to depict objects with RUWE values >1.3. The solid blue lines depict equivalence, while the dashed line shows the best linear fit to the data. The shaded area marks the region of 1σ standard deviation from the mean. In the fit, only data with good RUWE values were employed, that is the open symbols.
