Low-dispersion spectral sky survey to find faint carbon stars. III. Region 145 degree ≤ ell ≤ 165 degree, -5 degree ≤ b ≤ +5 degree

A low-dispersion spectral survey (1,250 angstrom/mm near Hγ) made with the 70-cm meniscus telescope in the region 145 degree ≤ ell ≤ 165 degree, -5 degree ≤ b ≤ +5 degree has revealed 172 carbon stars, of which 83 have been found for the first time. The distribution of the carbon stars in the investigated region with respect to latitude and longitude is uniform, and the surface distribution is a Poisson distribution. By the nearest-neighbor method it is shown that pairs of carbon stars and possible members of open clusters are not present in the investigated region. The latitude and longitude distributions of the carbon stars of the combined sample of all three regions investigated by the authors are analyzed
