THE SURFACE DISTRIBUTION OF CARBON STARS IN THE GALAXY

The results on the deep low dispersion (1250 ${\AA}$/mm at $H_r, $30^{\circ}$ < I < $165^{\circ}$, $195^{\circ}$ < I < $210^{\circ}$, [b] < $5^{\circ}$; 7000${\AA}$/mm at A band, $50^{\circ}$ < I < $115^{\circ}$, b=$0^{\circ}$, b=${\pm}3.5^{\circ}$) spectral surveys of the MILKY WAY are presented. More than 2250 carbon stars were identified among them 1440 new ones. The C/M5+ ratio increases from 0.02 to 0.3 when longitude varies from $30^{\circ}$ to $210^{\circ}$. On the basis of A GENERAL CATALOG OF GALACTIC COOL CARBON STARS the surface distribution of carbon stars has been studied.
