Overview of observations for the radio-loud blackbody quasar BBQSORS. Top: optical images collected from Subaru HSC-SSP, IR images collected from Spitzer, and VLASS radio images at 3 GHz observed at Epochs 2 and 3. The false-color image is rendered using HSC g + r + z, overlaid with the white contours representing the VLASS Epoch 2 imaging. The blue circle represents the PFS fiber with a diameter of ﹩1\mathop{.}\limits^{^{\prime\prime} }02﹩. Middle: Subaru/PFS spectrum of BBQSORS and fitted using S³Fit. Bottom: zoom-in of the Subaru/PFS spectrum C III]λ1909 and Mg IIλ2800, as well as best fits to the underlying continuum and emission/absorption, without incorporating the Fe II template. The spectra are Gaussian-smoothed by every nine data points. For absorptions of Al IIIλλ1855, 1863 and Mg IIλλ2796, 2803, we show their centers, FWHMs, and velocity shifts in the corresponding panels.
