TLDR
The second public data release (DR2) of the Calar Alto Legacy Integral Field Area (CALIFA) survey as discussed by the authors contains over 1.5 million spectra.Abstract:
This paper describes the Second Public Data Release (DR2) of the Calar Alto Legacy Integral Field Area (CALIFA) survey. The data for 200 objects are made public, including the 100 galaxies of the First Public Data Release (DR1). Data were obtained with the integral-field spectrograph PMAS /PPak mounted on the 3.5 m telescope at the Calar Alto observatory. Two different spectral setups are available for each galaxy, (i) a low-resolution V500 setup covering the wavelength range 3745-7500 A with a spectral resolution of 6.0 A (FWHM); and (ii) a medium-resolution V1200 setup covering the wavelength range 3650-4840 A with a spectral resolution of 2.3 A (FWHM). The sample covers a redshift range between 0.005 and 0.03, with a wide range of properties in the color-magnitude diagram, stellar mass, ionization conditions, and morphological types. All the cubes in the data release were reduced with the latest pipeline, which includes improved spectrophotometric calibration, spatial registration, and spatial resolution. The spectrophotometric calibration is better than 6% and the median spatial resolution is 2´´ 4. In total, the second data release contains over 1.5 million spectra.read more

TL;DR: In this article, the authors apply the fossil record method based on spectral synthesis techniques to recover the following physical properties for each spatial resolution element in the target galaxies: the stellar mass surface density (μ_*), stellar extinction (A_V), lightweighted and mass-weighted ages (L, M), and mass weighted metallicity (M).

The distribution of interstellar dust in CALIFA edge-on galaxies via oligochromatic radiative transfer fitting
Gert De Geyter,Maarten Baes,Peter Camps,Jacopo Fritz,Ilse De Looze,Thomas M. Hughes,Sébastien Viaene,Gianfranco Gentile,Gianfranco Gentile +8 more
TL;DR: In this paper, the authors investigate the amount and spatial distribution of interstellar dust in edge-on spiral galaxies, using detailed radiative transfer modelling of a homogeneous sample of 12 galaxies selected from the Calar Alto Legacy Integral Field Area survey.
Imfit: A Fast, Flexible New Program for Astronomical Image Fitting
TL;DR: It is shown that fitting low-S/N galaxy images using chi^2 minimization and individual-pixel Gaussian uncertainties can lead to significant biases in fitted parameter values, which are avoided if a Poisson-based statistic is used; this is true even when Gaussian read noise is present.
