Distribution of indicators of the luminosity class found by other authors for stars classified as giants by the FOSC. Top: distribution of log g found by Ga10. Bottom: distribution of luminosity classes found by SG12. The solid lines show the relative frequency of the log g value (luminosity class, respectively, for the bottom panel) in the whole sample stars classified as giants by the FOSC. The contribution from stars in the sample that have the luminosity class III with the FOSC is shown by the dashed line; the contribution of those of class II is indicated by the dotted line and the contribution of class I is indicated by the dashed-dotted line. The dashed, dotted, and dashed-dotted curves add up to the solid curve.
