26. F8
The spectral type is determined from the ratios 4045: H and 4226: H. The most sensitive criterion of absolute magnitude is probably the ratio 4077: 4226 for normal giants and dwarfs; while in the range from supergiants to giants the ratios 4077: H and 4171-4173: 4226 allow a very accurate luminosity classification to be made.
