Photometry and Spectroscopy of Elliptical Galaxies
Listed in IVOA Registry (Virtual Observatory)
Photometric and spectroscopic data are presented for a survey of the nearest and brightest elliptical galaxies.
Description
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-per-byte Description...", they are indicated by the page number (e.g., p765L).
