The Classification of Blazars Candidates of Uncertain Types
In this work, the support vector machine (SVM) method is adopted to separate BL Lacertae objects (BL Lacs) and flat spectrum radio quasars (FSRQs) in the plots of photon spectrum index against the photon flux, αph∼logF, that of photon spectrum index against the variability index, αph∼logV\!I, and that of variability index against the photon flux, logVI∼logF. Then we used the dividing lines to tell BL Lacs from FSRQs in the blazars candidates of uncertain types from \textit{Fermi}/LAT catalogue. Our main conclusions are: 1. We separate BL Lacs and FSRQs by αph=−0.123logF+1.170 in the αph∼logF plot, αph=−0.161logVI+2.594 in the αph∼logVI plot, and logVI=0.792logF+9.203 in the logVI∼logF plot. 2. We obtained 932 BL Lac candidates and possible BL Lac candidates, and 585 FSRQ candidates and possible FSRQ candidates. 3. Some discussions are given for comparisons with those in literature.
