Improved method to determine the integrated properties of nuclear rings:
  NGC 1512
  The integrated properties of nuclear rings are correlated with their host
galaxy's secular evolution and its dynamics, as well as with the formation and
evolution of the ring's star cluster population(s). Here we present a new
method to accurately measure the spectral energy distribution and current
star-formation rate (SFR) of the nuclear ring in the barred spiral galaxy NGC
1512 based on high-resolution {\sl Hubble} and {\sl Spitzer Space Telescope}
images. Image degradation does not have a significant negative effect on the
robustness of the results. To obtain the ring's SFR for the period spanning
$\sim$3--10 Myr, we apply our method to the continuum-subtracted H$\alpha$ and
8 $\mu$m images. The resulting SFR surface density, $\Sigma_{\rm
  SFR}$=$0.09\, {M}_{\odot} \,{\rm yr}^{-1}$ ${\rm kpc}^{-2}$, which is much
higher than the disk-averaged SFR densities in normal galaxies. We also
estimate the ring's total stellar mass, log (${M}/{M}_{\odot}$) = 7.1 $\pm$
0.11 for an average age of $\sim$40 Myr.
