Fully corrected SED in 7 bands for SDSS J081650.77+492859.2 (objid=587725980955967681) galaxy Fully corrected SED in 7 bands for SDSS J081650.77+492859.2 (objid=587725980955967681) galaxy at redshift 0.1794. 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 J081650.77+492859.2 (objid=587725980955967681) galaxy spectrum together with the emission lines fitting Nbursts full spectrum fitting for SDSS J081650.77+492859.2 (objid=587725980955967681) 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.
