Fully corrected SED in 10 bands for SDSS J152140.03+020816.2 (objid=587726015627854137) galaxy Fully corrected SED in 10 bands for SDSS J152140.03+020816.2 (objid=587726015627854137) galaxy at redshift 0.0509. Blue and red symbols represent total (Petrosian) and 3-arcsec fiber magnitudes correspondingly. The rest framed SDSS spectrum is overplotted and demonstrates a typical good agreement with the corrected fiber magnitudes for that galaxy. The inset shows an 36x36 arcsec optical SDSS false color image.

Nbursts full spectrum fitting for SDSS J152140.03+020816.2 (objid=587726015627854137) galaxy spectrum together with the emission lines fitting Nbursts full spectrum fitting for SDSS J152140.03+020816.2 (objid=587726015627854137) galaxy spectrum together with the emission lines fitting (gaussian model). Central panel shows an observed galaxy spectrum (black), the best fitting template (red) and residuals (blue). The observed and rest-frame wavelength are shown in the bottom and top of the plot respectively. Panels on the sides demonstrate recovered profiles after the continuum subtraction of individual emission lines (black) and the best-fitting models (red). Blue lines show emission line flux uncertainties. Vertical red dashed lines represent the galaxy redshift in the SDSS database. See also this spectrum with best-fit models in the interactive spectrum viewer.

BPT diagram for SDSS J152140.03+020816.2 (objid=587726015627854137) galaxy
Position of SDSS J152140.03+020816.2 (objid=587726015627854137) galaxy (shown as a star) on the BPT diagram with the color coded Hα equivalent width. Two or more stars mean that there are several spectra for this galaxy in the database. Here we display in the background only those galaxies from RCSED catalog where all emission lines used in the plot have signal-to-noise ratio S/N > 3. The contours correspond to the galaxy density smoothed with a moving average based on a 4-pixels window. The number of galaxies kept in the sample is indicated on the top left. The full and dashed lines correspond to starforming and transitional galaxies in Kewley et al. (2006).
