Description:
Photometric and spectroscopic data are presented for a survey of the
nearest and brightest elliptical galaxies. Distances, velocities
relative to the cosmic rest frame, and residual velocities relative to
a velocity-flow model are calculated for individual galaxies and
groups. Information is provided on the selection and completeness of
the target and observed samples. Both samples appear to be noticeably
deeper in the north than in the south. A new diameter system for
ellipticals is described that is easy to measure on survey prints and
is a useful indicator of B_T_ magnitude.
Important Notices:
* This catalog is NOT the same with that of printed, but is selected.
The original explanation file "a149.doc" from Burstein to Andernach
describes as follows: "This file contains a total of 483 galaxies
having relatively accurate Dn values (quality parameter 2 or better).
Of these 483 galaxies, 385 were used by Lynden-Bell et al. for studies
of the velocity field. The reasons why the 71 galaxies were excluded
from the final survey are detailed in Lynden-Bell et al., and range
from absence of velocity dispersions, a lower limit on velocity
dispersions, and a surface brightness limitation."
* However, the resultant number of galaxies by above elimination is 479,
so the number of records in this file is 479.
* In Lynden-Bell et al. (1988ApJ...326...19L), the following description
is seen (p25L) "Of them, 433 have measured velocity dispersions.
Galaxies with velocity dispersions less than 100 km/s ... eliminated
all 25 of them from final data set. ... (8 more galaxies are
eliminated due to various reasons)." The number of those galaxies
which have no velocity dispersion measurement (0.000 is written in
"logSIG" column) is 46, hence "71" (=46+25) as above. The number 400
(=479-71-8) coincides with that written in the top line of the
Abstract of Lynden-Bell et al. Therefore, the number of "483" written
above seems to be erroneous. The number "385" is seen in the Fig.1 of
Lynden-Bell et al.
* The values in column "B-V0" in the file "table1" are those corrected
according to the ERRATA (ApJS, 71,173 (1989)).
* Columns "n_{B-V}", "D_{FW}", "R_{FW}", "k", "M" and "Remarks" in the
published Table 1 are omitted in the file.
* The blank entries in the published Table 1 is filled, in this file, by
some unexpected values, such as 0 in columns "Ngr", "Vhel", "Vgr",
"B-V0", "SBe", "logSIG", "Mg2", or 0.10 in "BT", -0.99 in "logAe".
* The relevant data have been corrected for extinction, redshift and
cosmological effects, and "logSIG" and "Mg2" are corrected for
distance-dependent aperture effects, as detailed in Davies et
al. (1987ApJS...64..581D).
* For some columns of Table 1, detailed explanations are given in the
paper. In the following "Byte-by-byte Description...", they are
indicated by the page number (e.g., p765L).

Note (1): In the published Table 1, the consecutive number is given here.
However, the archived file is not consecutive because of the reason written
in the Notes of Description above. See paper p765L.
Note (2): the abbreviations are:
'N'=NGC, 'I'=IC, 'U'=UGC 'E&G'=ESO, 'A'=anonymous,
'CR'=Chincarini & Rood (1971ApJ...168..321C),
'D'=Dressler (1980ApJS...42..565D); the descriptions "Dressler (1983)"
in the paper should be read "Dressler (1980)", both in text and
in references.
Note (3): This is not that in Table 1, but the true one as described in
ERRATA (ApJS, 71,173 (1989))
