The scientific potential of KINGFISH derives from combining the power of deep infrared imaging with spectroscopy of the key diagnostic lines, and the vast ancillary data heritage SINGS. To maximize the benefits the KINGFISH imaging and spectroscopy have been closely tailored to the existing SINGS observations.

Our sample consists of galaxies within 30 Mpc, to assure multiple resolution elements across the galaxies, even at 500 micron. The galaxies were selected to fill a 3-parameter space of galaxy types, luminosity, and IR/optical ratio, and representative coverage in gas fraction, HI/H₂ ratio or bulge/disk/bar structure. The sample covers nearly two orders of magnitude in oxygen abundance (7.3 < 12 + log(O/H) < 9.3), four orders of magnitude in 3.6 μm luminosity (~10⁶ - 10¹⁰ L_⊙), and in total infrared luminosity (~4 x 10⁶ - 10¹¹ L_⊙), and a similar total range in SFRs (~0.001 - 7 M_⊙ yr⁻¹). Our spectroscopic targets were also chosen to cover as diverse a range in local ISM environments as possible.

For this project we observe only 57 of the 75 SINGS galaxies. We have added 4 other nearby galaxies that were not part of the SINGS sample (because they were in Spitzer GT samples). These add importantly to the range of physical properties covered by the KINGFISH sample, and possess similar Spitzer and ancillary data coverage as the SINGS galaxies.
