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
The Bochum Galactic Disk Survey is an ongoing project to monitor the
stellar content of the Galactic disk in a 6 degree wide stripe
centered on the Galactic plane. The data has been recorded since
mid-2010 in Sloan r and i simultaneously with the RoBoTT Telecsope at
the Universitaetssternwarte Bochum near Cerro Armazones in the Chilean
Atacama desert. It contains measurements of about 2x10^7 stars over
more than seven years. Additionally, intermittent measurements in
Johnson UVB and Sloan z have been recorded as well.
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.
The Armagh-Dunsink-Harvard Becker-Schmidt Telescope was deployed at
Boyden Station, Maselspoort South Africa between 1965 and 1970. During
that time, astronomers from Bamberg, Heidelberg, Hamburg and Münster
took astronomical images there, with a focus on old star clusters, the
Magellanic clouds, and the southern milky way. This service provides
scans of the plates obtained.
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.
The Calar Alto Legacy Integral Field Area (CALIFA) survey provides
spatially resolved spectroscopic information for 667 galaxies, mainly
within the local universe (0.005 < z < 0.03).
CALIFA data was obtained using the PPAK integral field unit (IFU), with a
hexagonal field-of-view of 1.3 square arcmin, with a 100% covering factor
by adopting a three-pointing dithering scheme. has been taken in two
setups: V500 (6 Å bin size, 646 galaxies) and V1200 (2.3 Å bin size, 484
galaxies). A final product ("COMBO") combining both data sets, covering
3700-7500 Å at 6 Å bin size, is made availble for 484 galaxies.
CALIFA is a legacy survey, intended for the community. This is the (final)
Data Release 3.
The overall goal of this tutorial is to become familiar with VOSpec.
For that, we are going to build the Spectral Energy Distribution (SED)
of two Herbig Ae/Be stars, compare them and categorise them as group 1
or group 2 Herbig Ae/Be stars.
