Documentation for the machine-readable version of the catalog of 5,268 standard stars, 1950.0 based on the normal system N30The machine-readable version of the N30 catalog available on magnetic tape from the Astronomical Data Center is described. Numerical representations of some data fields on the original catalog were changed to conform more closely to formats being used for star-catalog data, plus all records having asterisks indicating footnotes in the published catalog now have corresponding remarks entries in a second tape file; i.e. the footnotes in the published catalog were computerized and are contained in a second file of the tape.
