Number of sources in the 1FGL catalog for specific criteria.
  Number Percentage
All 1451 100%
$F_{10{-}100~\rm GeV}$ 287 20%
z 390 27%
$F_{10{-}100~\rm GeV}$+ z 72 5%
$F_{10{-}100~\rm GeV}$+ z + NC 57 4%
$F_{10{-}100~\rm GeV}$+ z + C 15 1%
FSRQs    
$F_{10{-}100~\rm GeV}$+ z + NC 12 <1%
$F_{10{-}100~\rm GeV}$+ z + C 6 <1%

Notes.  $F_{10{-}100~\rm GeV}$- significant flux in the highest energy bin; z - known redshift; NC - no significant curvature detected in the spectrum; C - significant curvature detected in the spectrum; FSQR - source is of type FSRQ.
