Abstract:
We present R-band CCD photometry for 1332 early-type galaxies,
observed as part of the Early-type NEARby galaxies (ENEAR) survey of
peculiar motions using early-type galaxies in the nearby universe.
Circular apertures are used to trace the surface brightness profiles,
which are then fitted by a two-component bulge-disk model. From the
fits, we obtain the structural parameters required to estimate galaxy
distances using the Dn-σ and fundamental plane relations.
The photometric data reported here represent one of the largest
high-quality and uniform all-sky samples currently available for
early-type galaxies in the nearby universe, especially suitable for
peculiar motion studies.
Description:
The RC-band (Kron-Cousins) photometry reported in this paper was
obtained over 100 photometric or partially photometric nights out of a
total of 177, using several telescopes over various observing runs in
the period 1987-1999.
