Description:
We study the synchrotron component of the spectral energy distribution
on the sample of 877 blazars using ASDC SED Builder Tool with
available broadband data from the literature. Our sample includes 423
flat-spectrum radio sources (FSRQs), 361 BL Lac objects and
candidates, and 93 blazars of uncertain type. We have made an
estimation of the synchrotron peak frequency for the 875 objects and
further classified them as high, intermediate and low synchrotron
peaked sources (HSPs/ISPs/LSPs). For each source NVSS name (RA
(HHMMSS) and DEC (DDMMSS) for the J2000.0 epoch), alias, redshift, R
band magnitude, synchrotron peak frequency, correlation coefficient,
flux density at 4.8GHz, SED class, blazar type and selection method
are presented.

Note (1): Correlation strength between observational data points in SED
and polynomial approximation (from ASDC SED Builder Tool)
Note (2): R band magnitude and blazar type according to the Roma-BZCAT
catalogue 3d edition (2009A&A...495..691M 2009A&A...495..691M, Cat. J/A+A/495/691)
Note (3): Blazar type as follows:
RBL = radio-selected BL Lac
XBL = X-ray-selected BL Lac
OBL = optically-selected BL Lac
Note (4): Classification as follows:
HSP = high synchrotron peaked
ISP = intermediate synchrotron peaked
LSP = low synchrotron peaked
