  • 摘要:In this paper, we determine the distances to Camelopardalis area and generates the mean absolute magnitudes and the dispersions for the spectral types and subtypes. The method of calculation depends on the assumption that absolute magnitudes and apparent magnitudes follow a Gaussian distribution function. The effect of Malmquist bias has been studied to show what extent bias is effective in comparison. We estimate the distances and generate the mean absolute magnitude and dispersions of all spectral types and subtypes. The nonsystematic difference between the calculated distances for different spectral types are remarkable, this may be attributed to the different chemical compositions and evolution scenarios of each spectral type.
