Abstract:
We provide single-epoch spectroscopic data for a sample of 13
lensed quasars. The sources have bolometric luminosities between
1044.7-47.4erg/s and black hole masses 107.6-9.8M_☉.
These spectra have been used to perform a systematic search for
microlensing in the broad line region. The spectra have been deblended
using the MCS advanced deconvolution technique. We provide the
extracted and flux calibrated spectra, and the 2D deconvolved frames,
separating the point-like emission from the extended emission (from
the residual sky and from the lensing galaxy).
Description:
Extracted flux calibrated spectra of 13 lensed quasars following
the methodology described in Sect. 2.1. of the oaoer. The data
were obtained with the FORS spectrograph at VLT in multi-object
spectroscopy mode. The typical wavelength coverage is from 4200
to 8200Å. The data concern the following objects: HE0047-1756
(HE0047), Q0142-100 (Q0142), SDSSJ0246-0825 (SDSS0246),
HE0435-1223 (HE0435), SDSSJ0806+2006 (SDSS0806), FBQ0951+2635
(FBQ0951), BRI0952-0115 (BRI0952), SDSSJ1138+0314 (J1138),
J1226-0006 (J1226), SDSSJ1335+0118 (J1335), Q1355-2257 (Q1355),
WFI2033-4723 (WFI2033), and HE2149-2745 (HE2149). For each object,
we provide the 1D flux calibrated spectrum of the 2 individual
images in the slit. In addition, we also provide the 2D reduced
spectrum and corresponding 1σ error frame (corresponding
files are named "objectname_data" and "objectname_err"), and the
2D processed spectra associated to the deconvolution, as shown in
Fig.1 of the paper. These processed 2D spectra are the deconvolved
frame ("_dec"), the extended component of the flux emission ("_ext")
and the residual frame in σ units ("_res") corresponding to
panel (b), (c) and (d) of Fig.1. A pdf file file similar to Fig.1
is also provided for each object.
