The Classification

The command CLASSIFY/INV performs a classification of listed objects on stars, galaxies, members of a broad class of defects, and unclassified---mostly very faint---objects. Only the table produced by the ANALYSE/INV command can be used as input for the CLASSIFY/INV command. An additional column containing the result of the classification will be appended to this table. The user can have some influence on the resulting classification by setting few keywords. In some cases it is known beforehand what kind of objects predominate at the faintest magnitudes where accurate classification is impossible. Proper setting of keywords CLASSPAR and DISTANCE can accomplish subjective segregation of the faintest objects into stars and galaxies. The results of classification are reliable only for objects that are considerably brighter than the limiting magnitude.

The following additional keywords can be set with the help of the SET/INV C command:
