SPECTROPHOTOMETRY OF CARBON

The results of a spectrophotometric study of 13 carbon stars in the wavelength range from 4000 A^o to 6800 A^o with 2.75 A resolution are given. The observed energy distributions for these stars relative to the flux at lambdal(o) = 5556 A, represented in graphic form, were determined. Their color temperatures were determined from the [5710] - [6680] color index. A dust shell is assumed to exist around U Cyg. The indices of the C(2) MS. and CaCl molecular bands and the D(2.1) line were also determined,
