The archive of AGN spectral observations is obtained on AZT-8
telescope at the Fesenkov Astrophysical Institute (FAI), Almaty,
Kazakhstan. It represents the result of observations for abot 25 years
- from 1970 to 1995. All observations were carried out at AZT-8 (D =
700 mm, F[main] = 2800 mm, F[Cassegrain] = 11000 mm) with a high-power
spectrograph. In 1967-68, on the basis of the image intensifier
(https://doi.org/10.1080/1055679031000084795a) developed and assembled
the spectrograph of the original design in the workshops of the FAI.
To use the spectra, please, download raw .fit file of required object,
date and exposure. The open 'Calibration frames' in Related links and
then use them to calibrate object spectra frames. For more information

1BIGB: First Brazil-ICRANet Gamma-Ray Blazar Catalogue

Description:
This catalog presents the 1-100 GeV spectral energy distribution (SED)
for a population of 148 high-synchrotron-peaked blazars (HSPs) recently
detected with Fermi-LAT as part of the
First Brazil-ICRANet Gamma-ray Blazar catalogue (1BIGB).
A series of two works describe details on the broadband analysis:
:bibcode:`2017A&A...598A.134A`, and the calculation of the
gamma-ray SEDs :bibcode:`2018MNRAS.480.2165A`.
The 1BIGB sample was originally selected from an excess signal in the
0.3-500 GeV band The flux estimates presented here are derived considering
PASS8 data, integrating over more than 9 years of Fermi-LAT observations. The
full broadband fit between 0.3-500 GeV presented in paper 1 for all sources
was reevaluated in paper 2, updating the power-law parameters with currently
This service exposes the light curves of stars produced by the Bochum
Galactic Disk Survey; several million light curves are provided in the
SDSS i and r bands. The lightcurves are published per-band and are
also available through obscore.
Split spectra from the CALIFA DR3 cubes. This service serves one
spectrum each per pixel in each cube where there is at least one valid
spaxel. Where both V500 and COMB data is available, COMB spectra are
served. WARNING: The individual spectra are not independent. Also,
error estimates over wide spectral ranges based on the error estimates
served here are unreliable.
Coordinated microlensing survey observations with Kepler K2/C9 using
VST

Description:
The Kepler satellite has observed the Galactic center in a campaign
lasting from April until the end of June 2016 (K2/C9). The main
objective of the 99 hours for the microlensing program 097.C-0261(A)
using the ESO VLT Survey Telescope (VST) was to monitor the superstamp
(i.e., the actually downloaded region of K2/C9) in service mode for
improving the event coverage and securing some color-information. Due
to weather conditions, the majority of images were taken in the red
band. These are part of the present release.
The exact pointing strategy was adjusted to cover the superstamp with
6 pointings and to contain as many microlensing events from earlier
seasons as possible. In addition, a two-point dither was requested to
reduce the impact of bad pixels and detector gaps. Consequently, some
events were getting more coverage and have been observed with
different CCDs. The large footprint of roughly 1 square degree and the
complementary weather conditions at Cerro Paranal have lead to the
coverage of 147 events (this resource's events table), but ~60 of
those were already at baseline.
Digitized First Byurakan Survey (DFBS) Spectra Query Service

Description:
The First Byurakan Survey (FBS) is the largest and the first systematic
objective prism survey of the extragalactic sky. It covers 17,000 sq.deg.
in the Northern sky together with a high galactic latitudes region in the
Southern sky. The FBS has been carried out by B.E. Markarian, V.A.
Lipovetski and J.A. Stepanian in 1965-1980 with the Byurakan Observatory
102/132/213 cm (40"/52"/84") Schmidt telescope using 1.5 deg. prism. Each
FBS plate contains low-dispersion spectra of some 15,000-20,000 objects;
the whole survey consists of about 20,000,000 objects.
