Query: Near-Infrared photometry in the J, H and Kn bands for Polar Ring
  Galaxies: I. Data, structural parameters   We present new Near-Infrared (NIR) observations, in the J, H and Kn bands,
for a sample of Polar Ring Galaxies (PRGs), selected from the Polar Ring
Catalogue (Whitmore et al. 1990). Data were acquired with the CASPIR near-IR
camera at the 2.3 m telescope of Mount Stromlo and Siding Spring Observatory.
We report here on the detail morphological study for the central host galaxy
and the polar structure in all PRGs of our sample. Total magnitudes,
bulge-to-disk decomposition and structural parameters are computed for all
objects. These data are crucial for an accurate modeling of the stellar
population and the estimate of the star formation rates in the two components.
