Note on name:
NGC designation
IC designation
UGC (Nilson 1973) designation
Coordinate designation preceded by A (Fisher and Tully 1981)
Coordinate designation preceded by E (Lauberts et al. 1981, and
references cited therein; ESO/Uppsala Survey)
Note on RA* and DE*:
A majority of the positions given were newly determined by Aaronson et
al. (1982). Objects without positions measured by the authors of the
these authors will have a note indicating the source of the coordinates
given.
Note on type:
In the revised Hubble system (de Vaucouleurs et al. 1976; RC2), using
the notation of the RC2.
Note on incli:
Generally this was determined from axial ratios. See Aaronson et al.
(1982) for details of the method used and for further references.
Note on mag:
No correction has been applied for internal galactic absorption, but the
photometry has been corrected for both galactic extinction and for
redshift effect on the isophotal diameter . . . . See Aaronson et al.
(1982) for a discussion of the correction applied, of the errors
expected, and of the references used in determining this value.
Note on log_d:
The isophotal diameters . . . are obtained from the RC2, unless noted
otherwise . . . . The D1 system is essentially the same as the D0 system
of the RC2, differing only in the galactic extinction correction and in
the use of a cutoff term applied to objects at high inclination . . . .
See Aaronson et al. (1982) for a discussion of the transformations used
on data from different sources and of likely sources of error.
Note on redsh:
Measured for neutral hydrogen and stated as a heliocentric velocity in
km/sec.
Note on width:
HI velocity width, in km/sec, corrected for inclination and (1 + z)
expansion effect.
See Aaronson et al. (1982) for details of the corrections applied and
for a discussion of agreement between observers and of possible sources
of error.
Note on HI:
Observed HI flux density integral, in Jy km/sec, corrected for the
effects of partial resolution by the telescope beam.
See Aaronson et al. (1982) for details of how the data were selected to
ensure consistency.
Note on dist:
Ratio of the distance of the galaxy to the distance of Virgo. The
distances relative to Virgo are calculated from redshifts and from the
infall model discussed in @Aaronson et al. 1982, Astrophys. J., in
press; . . . . Because of restrictions imposed by the model used, those
galaxies with galactocentric redshifts below 300 km/sec and/or lying
within a conical shell between 6 deg. and 25 deg. from Virgo were
excluded from these calculations. For these galaxies, this field is
blank.
Note on source:
The source(s) of the HI data listed are cited here by a character code
up to three letters long. The corresponding references are listed by
code as follows:
ADM Aaronson et al. 1981.
AHM Aaronson, Huchra, and Mould 1979.
CRW Cram, Roberts, and Whitehurst 1980.
DR Dickel and Rood 1978.

P1 Aaronson, Mould, and Huchra 1980.
P2 Mould, Aaronson, and Huchra 1980.
P3 Aaronson et al. 1980.

SA Shostak and Allen 1980.
TF Fisher and Tully 1981.
VW van Woerder et al. 1982.
WG Whiteoak and Gardner 1977.
Note on group:
A group assignment is listed here only if at least two members of the
group are present.
See Aaronson et al. (1982) for a discussion of how group assignments
were determined.
Note on note:
Notes are cited by code number. Many galaxies have no notes at all,
while some have as many as four. The codes are as follows:
1. Position from de Vaucouleurs and Leach 1981.
2. Position from Gallouet, Heidmann, and Dampierre 1975 (and
references cited therein).
3. Morphological type adopted from the UGC.
4. Diameter and axial ratio obtained from the UGC.
5. Morphological type adopted from Nilson 1974.
6. Diameter and axial ratio obtained from Nilson 1974.
7. Morphological type adopted from Lauberts et al. 1981.
8. Diameter and axial ratio obtained from Lauberts et al. 1981.
9. Position from Lauberts et al. 1981.
10.Morphological type assigned by Aaronson et al. (1982).
11.Diameter and axial ratio obtained from mean of Lauberts et al. 1981
and Nilson 1974 data.
12.H-0.5 estimated from average of data and mean growth curve extrapolation.
13.Position from Dressel and Condon 1976.
14.The S0 type in RC2 is a misclassification; spiral arms are clearly
visible in the ESO blue plate.
Remarks and Modifications:
The catalog was received by the Astronomical Data Center (ADC), NASA
Goddard Space Flight Center, from the Centre de Donnee Astronomiques,
Strasbourg (CDS), in February 1986.
The original tape contained a single text file in a format identical to
that of the published paper. An editor was used to expand abbreviations,
to reformat the note field, and to compress the data file from 124 to
111-byte records by removing blank columns. The record for object NGC
4124, omitted from the original tape file received by the ADC, was
located in the published catalog and re-inserted into this distribution
version of the catalog. A FORTRAN program was run that checked the
validity of each field according to its data type and value.
This work and the preparation of the original document was performed by
Anne C. Raugh. The undersigned translated the document from a Script
form available in hard copy only to the current ASCII document.
