The name of the galaxy. Following the RC1 and RC2, galaxies that appear in the NGC and IC catalogs are listed using their NGC or IC designations. Non-NGC or -IC galaxies that are listed in the Zwicky catalog or the UGC have been given an IAU style coordinate name of the form HHMMm+DDMM where HHMMm is the RA in hours, minutes and tenths of minutes, and +DDMM (or -DDMM) is the declination in degrees and arcminutes. These coordinate names are derived from the original Zwicky catalog position, even if a more accurate position has been measured. Bright anonymous galaxies which are not in Zwicky or the UGC are designated as AHHMM+DDMM, i.e., with a leading "A" and no fractional minutes. The HEASARC has added the Dictionary of Nomenclature of Celestial Objects recommended prefix for objects in this catalog of "[HVG99b]".
The Right Ascension of the galaxy in the selected equinox. This was given in B1950 coordinates and to a precision of 0.1 seconds of time in the original table. These coordinates are primarily from the Zwicky catalog. For brighter galaxies, for Markarian galaxies, for some objects with improved coordinates in the PGC and RC3, and for many objects from the DSS whose positions have been measured, improved coodinates are listed.
The Declination of the galaxy in the selected equinox. This was given in B1950 coordinates and to a precision of 1 arcsecond in the original table. These coordinates are primarily from the Zwicky catalog. For brighter galaxies, for Markarian galaxies, for some objects with improved coordinates in the PGC and RC3, and for many objects from the DSS whose positions have been measured, improved coodinates are listed.
The Galactic Longitude of the galaxy.
The Galactic Latitude of the galaxy.
The apparent blue magnitude in the Zwicky-B(0) system (Huchra 1976, AJ, 81, 952). These magnitudes are from the RC1 or the merged Zwicky-Nilson catalog, unless otherwise noted by the presence of a non-blank code in the ref_bmag parameter.
This parameter contains a code for a magnitude reference if the magnitude is not from either the RC1 or the merged Zwicky-Nilson catalog, where "B" means that the quoted value is a B_T magnitude which has been converted to the B(0)-Zwicky system, "H" that it is a split Zwicky magnitude (for multiple galaxies), "M" that it is from Markarian and Lipovetskii (1974) and "S" that it is from Sakai, Giovanelli and Wegner (1994).
The heliocentric radial velocity of the galaxy, in km/s.
The RMS uncertainty in the heliocentric radial velocity, in km/s.
A code for the reference for the radial velocity. The key to the codes is given in Table 2 of the published paper and is also available at ftp://cdsarc.u-strasbg.fr/pub/cats/J/ApJS/121/287/refs.dat.gz
The numerically coded, revised Hubble (morphological) Type of the galaxy. Numerically coded Hubble types were introduced in the RC2 and the correspondence of these codes to the Hubble types are as follows:
Code: Definition -7: Unclassified elliptical -6: Compact elliptical -5: E, dwarf elliptical -4: E/S0 -3: L-, SO- -2: L, SO -1: L+, SO+ 0: SO/a, SO-a 1: Sa 2: Sab 3: Sb 4: Sbc 5: Sc 6: Scd 7: Sd 8: Sdm 9: Sm, Magellanic spiral 10: Im, Irr I, Magellanic irregular, Dwarf irregular 11: Compact irregular, extragalactic H II region 15: Peculiar, unclassifiable 16: Irr II 20: S..., Sc-Irr, unclassified spiral
The numerically coded, revised Hubble (bar) Type of the galaxy. Numerically coded Hubble types were introduced in the RC2 and the correspondence of these codes to the Hubble types are as follows:
Code: Definition A: A, unbarred X: X, AB, mixed type B: B, barred
The numerically coded, revised Hubble (peculiarity) Type of the galaxy. Numerically coded Hubble types were introduced in the RC2 and the correspondence of these codes to the Hubble types are as follows:
Code: Definition P: Peculiar S: No inner ring R: Ringed (outer) U: Unclassifiable T: Pseudo inner ring D: Double or multiple
The numerically coded luminosity class of the galaxy, according to the following scheme used for spirals and irregulars:
Code: Definition 1: I 2: I-II 3: II 4: II-III 5: III 6: III-IV 7: IV 8: IV-V 9: V
The major axis diameter of the galaxy, in arcminutes.
The minor axis diameter of the galaxy, in arcminutes.
The UGC number of the galaxy.
The multiplicity index for the UGC equivalent.
This parameter includes comments, notes, and references to other catalogs, Note that there are 9 objects included in this table which are misclassified galaxies that were originally listed in table 4 of the published paper: 20372+2704A, 20372+2704B, 20393+0525, 21256+0823, 21296+3418, 21298+2955, 21478+3443, 22341+7523 and 23061+4638. Discrepant velocities are listed here along with the reference to their source. These entries look like "nnnn mm (xxx)", where nnnn is the velocity, mm is the quoted error (if any) and xxx is the source of the discrepant velocity. Additional notes are available in the Table 3 of the published paper, and are also available in the file ftp://cdsarc.u-strasbg.fr/pub/cats/J/ApJS/121/287/notes.dat.gz Other object designations given here include:
HCG = Hickson compact group, MK = Markarian, KDG = Karachentsev double galaxy, VV = Vorontosov-Velyaminov interacting galaxy, AK = Arakelian high surface brightness galaxy, Zw = Zwicky compact or peculiar galaxy, EMSS = Einstein Medium Sensitivity Survey, Kaz = Kazarian galaxy, etc.
