Abstract:
The relation between X-ray luminosity and near-infrared (NIR)
luminosity for early-type galaxies has been examined. NIR luminosities
should provide a superior measure of stellar mass compared to optical
luminosities used in previous studies, especially if there is
significant star formation or dust present in the galaxies. However,
we show that the X-ray-NIR relations are remarkably consistent with the
X-ray-optical relations. This indicates that the large scatter of the
relations is dominated by scatter in the X-ray properties of
early-type galaxies, and is consistent with early-types consisting of
old, quiescent stellar populations.
We have investigated scatter in terms of environment, surface
brightness profile, Mg2, Hβ, Hγ line strength indices,
spectroscopic age and nuclear Hα emission.

Apparent magnitudes were converted to luminosities using the
distances in column 2 (see the text for details).
Note (4): Flag not explained in the paper, for NGC 3557, logLKs=logLH=10.89.
Apparently, not a Ks or H luminosity.
Note (5): All values are from O'Sullivan et al. (2001, Cat. J/MNRAS/328/461),
however, some of these were derived from the catalogues

Note (6): Environment following O'Sullivan et al. (2001, J/MNRAS/328/461):
F = field galaxy
G = group member (based on Garcia (1993, Cat. J/A+AS/100/47)
C = cluster member (based on Abell et al. (1989, Cat. VII/110)
and Faber et al. (1989, Cat. VII/176)
D = distance>70Mpc (for which environment cannot be accurately
determined).
Note (7): Environment defined as follows:
G = Brightest group galaxies from Garcia (1993, Cat. J/A+AS/100/47)
C = brightest cluster galaxies from Abell et al. (1989,
Cat. VII/110) and and Faber et al. (1989, Cat. VII/176)
D = dwarfs (LB<10^{9} LB☉)
A = AGN from Veron-Cetty and Veron, 2001A&A...374...92V 2001A&A...374...92V, VII/224,
as given in O'Sullivan et al. (2001, Cat. J/MNRAS/328/461)
