Abstract:
We present a deep near-infrared (NIR; J, H, and Ks bands)
photometric catalogue of sources from the Parkes HI Zone of Avoidance
(HIZOA) survey, which forms the basis for an investigation of the
matter distribution in the Zone of Avoidance. Observations were
conducted between 2006 and 2013 using the Infrared Survey Facility
(IRSF), a 1.4-m telescope situated at the South African Astronomical
Observatory site in Sutherland. The images cover all 1108 HIZOA
detections and yield 915 galaxies. An additional 105 bright 2MASS
galaxies in the southern ZOA were imaged with the IRSF, resulting in
129 galaxies. The average Ks-band seeing and sky background for the
survey are 1.38-arcsec and 20.1mag, respectively. The detection rate
as a function of stellar density and dust extinction is found to
depend mainly on the HI mass of the HI detected galaxies, which in
principal correlates with the NIR brightness of the spiral galaxies.
The measured isophotal magnitudes are of sufficient accuracy (errors
∼0.02mag) to be used in a Tully-Fisher analysis. In the final
NIR catalogue, 285 galaxies have both IRSF and 2MASS photometry (180
HIZOA plus 105 bright 2MASX galaxies). The Ks-band isophotal
magnitudes presented in this paper agree, within the uncertainties,
with those reported in the 2MASX catalogue. Another 30 galaxies, from
the HIZOA northern extension, are also covered by UKIDSS Galactic
Plane Survey (GPS) images, which are one magnitude deeper than our
IRSF images. A modified version of our photometry pipeline was used to
derive the photometric parameters of these UKIDSS galaxies. Good
agreement was found between the respective Ks-band isophotal
magnitudes. These comparisons confirm the robustness of the isophotal
parameters and demonstrate that the IRSF images do not suffer from
foreground contamination, after star removal, nor underestimate the
isophotal fluxes of ZoA galaxies.
Description:
Data acquisition started in 2006 and was completed by 2013, resulting
in deep NIR imaging of all the HIZOA targets. The images have exposure
times of 10-min, and are 2mag deeper than 2MASS in the Ks-band .
