Book Description
4. Census of the Catalogue The catalogue contains information on 277 objects. 137 (50%) of them are stars whose outburst spectra or unambiguous mInImUm characteristics classify them as novae beyond doubt. 123 of them could be identified at minimum. 78 (28 %) are stars with amplitudes and light curve forms which makes nova classifi cation likely. 60 of them could be identified at minimum. Thus, 78 % ofthe objects in this catalogue are confirmed and suspected classical novae. 16 (6%) have properties compatible with both novae and related objects. 15 are identified at minimum. Furthermore, the catalogue and atlas contains data on 12 (4 %) dwarf novae of long cycle length or suspected dwarf novae for which only one outburst has been observed. Examples are WZ Sge and CI Gern. 6 (2%) recurrent novae or suspected recurrent novae are listed. Examples are T CrB and AS Psc. 6 (2%) X-ray novae are listed. Examples are V616 Mon and KY TrA. 6 (2%) symbiotic stars and symbiotic novae are listed. Examples are RT Ser and V352 Aql. 11 (4 %) Mira stars or suspected Mira stars, which at some time were believed to be novae, are listed. Examples are V607 Aql and V927 Sgr.

Book Description
H h This third volume of RC3 indudes data for galaxies between 12 and 24 . For convenience, we repeat the explanation of the catalogue entries below. Details of the reduction procedures, and Notes, References, and Appendices are in Volume 1. 2. The Catalogue The data for each galaxy are found on four successive lines on a single page. The entries are as follows: Column 1: Positions Line 1: RA and DEC = right ascension and dedination for the equinox 2000.0, precessed from the 1950.0 position in Column 1, Line 4, given to 0.1 second of time and 1 arcsec when available, and to 0.1 minute of time and 1 arcmin otherwise (Section 3.1.a). Line 2: land b = galactic longitude and latitude in the lAU 1958 system (Blaauw et al. 1960); both to O~O1. Line 3: SGL and SGB = supergalactic longitude and latitude in the RC2 system (Section 3.1.b), both to O~O1. Line 4: RA and DEC = right ascension and dedination for the equinox 1950.0 (Sec tion 3.1.a). Column 2: Names = commonly used designations for the galaxies (Section 3.2). Line 1: Names (e.g., LMC, SMC) or NGC and IC designations. Line 2: UGC (Nilson 1973), ESO (Lauberts 1982), MCG (Vorontsov-Velyaminov et al. 1962-1974), UGCA (Nilson 1974), and CGCG (Zwicky et al. 1961-1968) des ignations, given in that order of preference. MCG designations not listed here are given in UGC and ESO.
