Examples of spectral energy distributions of sample stars. ATLAS9-SEDs, normalised in V and reddened according to values from Table 5 (blue lines) are compared to IuE spectrophotometry (grey lines) and photometric data in various wavelength bands: ANS (circles), TD1 (diamonds), Johnson (squares), 2MASS (triangles), and ALLWISE data (hexagons). Data with bad quality flags were removed. For better visibility, the SEDs and photometry of HD 164353 and HD 7902 were shifted by +1 and −1 dex, respectively.
