I/157       U.S. Naval Observatory Zodiacal Zone Catalog (ZZCAT; USNO 1990)

The U.S. Naval Observatory Zodiacal Zone Catalog Douglass G.G., Harrington R.S. <Astron. J., 100, 1712 (1990)> =1990AJ....100.1712D
ADC_Keywords: Positional data ; Proper motions Description: The catalog provides positions and proper motions at equinox and epoch J2000.0, on the FK5 system, for stars in the magnitude range 4-10, lying within 16 degrees of the ecliptic and north of declination -30 degrees. In order that references to earlier catalogs can be made, the B1950.0 positions and proper motions are given in both the FK5 and the FK4 systems. Other useful information, such as visual magnitudes and spectral types, is also provided. Stellar identification is strictly by Durchmusterung number, and the catalog is ordered by J2000.0 right ascension. It is important to understand that the present catalog does not cover the entire zodiacal zone, since stars south of zone -29 degrees could not be observed from the Washington site. These will be observed from the USNO Black Birch station in New Zealand commencing in 1991. File Summary:
