Abstract:
A deep Ks-band photometric catalogue of galaxies at the core of the
rich, nearby Norma cluster (ACO3627) is presented. The survey covers
about 45x45arcmin2 (slightly less than 1/3 Abell radius), which
corresponds to ∼0.8h70-2Mpc2 at the adopted distance
(vCMB/H0) of 70h70-1Mpc of this cluster. The survey is
estimated to be complete to a magnitude of MKs≲-19.5mag. This
extends into the dwarf regime, 6mag below M*Ks. The catalogue
contains 390 objects, 235 of which are classified as likely or
definite galaxies and 155 as candidate galaxies.
Description:
A survey of the Norma cluster in the NIR was undertaken with the
Simultaneous three-colour InfraRed Imager for Unbiased Surveys
(SIRIUS) on the Infrared Survey Facility (IRSF), the 1.4-m Japanese
telescope at the South African Astronomical Observatory (SAAO) site in
Sutherland. The observations were made during three observing runs in
June and July 2001 and July 2002.

Note (1): if a corresponding object was found in their deep optical search
of the SRC IIIaJ sky survey plates
Note (2): If an object is identified in more than one field, the magnitude
given is the average of the data from all fields in which the
photometric flag is zero.
Note (3): The typical 1σ uncertainty associated with these magnitudes
is 0.5mag
Note (4): as estimated from SExtractor's ISOAREA parameter:
D~=2Aiso=sqrt(ISOAREA*ELONGATION/π) where
Aiso is the isophotal semi-major axis, ISOAREA is the isophotal area
and ELONGATION is the ratio of the semi-major and semi-minor axes.
Note (5): The flag indicates the reliability of photometry in each image
in which the object was detected, as follows:
0 = reliable photometry
1 = neighbouring objects may have an influence on the photometry
of the object
2 = object was originally blended with another object
3 = neighbouring objects may have an influence on the photometry
of the object and object was originally blended with another object
4 = at least one pixel is saturated,
8 = object was truncated due to proximity to the boundary of an image
16 = object's aperture data is incomplete or corrupted
18 = object's aperture data is incomplete or corrupted
and object was originally blended with another object
19 = object's aperture data is incomplete or corrupted
and neighbouring objects may have an influence on the
photometry of the object
and object was originally blended with another object
24 = object's aperture data is incomplete or corrupted
and object was truncated due to proximity to the boundary of
an image
27 = object's aperture data is incomplete or corrupted
and neighbouring objects may have an influence on the
photometry of the object
and object was originally blended with another object
and object was truncated due to proximity to the boundary of
an image
32 = object's isophotal data is incomplete or corrupted
