Table 2.

Results of power-law fits of the blazar log N–log S distributions.

Sample	Fitted sources	Normalization A [10⁻³ deg⁻²]	Slope ^(a)	Original sample
MOJAVE-1, BAT	70	8.25 ± 0.57	1.13 ± 0.04	Lister et al. (2009a)
MOJAVE-1.5, BAT	92	9.22 ± 0.45	1.13 ± 0.03	Lister et al. (2013)
BAT cat. (beamed AGN)	143	46.20 ± 2.50	1.24 ± 0.02	Oh et al. (2018)
BAT cat. (beamed AGN, excl. MOJAVE-1)	115		1.38 ± 0.03	Oh et al. (2018)
BAT cat. (AGN)	955		1.27 ± 0.01	Oh et al. (2018)
MOJAVE-1 ^(a)	40			Lister et al. (2009a)
MOJAVE-1 ^(b)	32			Lister et al. (2009a)
MOJAVE-1.5	170			Lister et al. (2013)

Notes. The first two rows are fits to the BAT flux data (20 keV–100 keV), the three rows corresponding to the BAT catalog are fitted to the BAT flux catalog data set (14 keV–195 keV), and the last group of three rows are fits to the 15 GHz flux density data.

^(a)

Source selection based on all 125 MOJAVE-1 blazars. Sources with a VLBI flux density less than 2.5 Jy are excluded.

^(b)

Source selection based on all 70 MOJAVE-1 blazars that provide flux non upper limits in the BAT band. Sources with a VLBI flux density less than 2.5 Jy are excluded from the fit.
