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&amp;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</description><source> 2018MNRAS.480.2165A</source><referenceURL>http://dc.g-vo.org/onebigb/q/web/info</referenceURL><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://org.gavo.dc/__system__/obscore/obscore">GAVO Data Center Obscore</relatedResource></relationship></content><facility>Fermi FGST</facility><instrument>Fermi LAT</instrument><coverage><spatial>5/7 28 34 179 243 562 1010 1024 1047 1168 1176 1243 1551 1590 1816
