I/57          Abbadia Catalogue of 14263 Stars, +16 to +24°  (Hendaye 1915)

Catalogue de 14263 Etoiles comprises entre +16 et +15° Hendaye <Imprimerie de l'observatoire d'Abbadia (1915)>
ADC_Keywords: Positional data Description: This catalog contains meridian circle observations of 14192 reference stars in the Paris Observatory zone of the Astrographic Catalog, +16 to +24deg, made from 1899 to 1906. The original catalog contains also a supplement of 81 stars, which is not included here. The positions have been reduced to 1900.0 on the basis of Newcomb's constants. The probable errors for most stars range from 0.0093s to 0.0161s in right ascension and from 0.096" to 0.162" in declination, depending on the number of observations. In addition to the positions, the catalog contains a running number, the magnitude from the Berlin catalogs, the mean epoch and number of observations, and the BD number. File Summary:

Note (1): for bright stars, BDno contains the Flamsteed number and BDz is blank; in this case, the printed version includes the constellation name which is not reported here. In practice it just means that the BD numbers of bright stars are not reported in this catalog.
