J. 80 1011 1975 1975AJ.....80.1011H Plate data Stars, carbon Stars, S Surveys Eight hundred thirty-one infrared sources located south of +5deg have been selected from the Two-Micron Sky Survey (IRC), and studied in an objective-prism survey. The set consists of all 551 sources which were not identified in the IRC, 97 source whose identification in the IRC is questionable, and 183 sources identified by their variable-star catalog name, but for which no classification is given in the IRC. The great majority (89%) of the sources studied are M stars, but 49 carbon stars and seven S stars as well as 17 peculiar stars with emission near 8600A have also been identified. If available, recent classifications or identifications from other investigators are included
