We used the artificial neural network technique (ANN), based on B-=
FlaP algorithm developed in http://adsabs=
.harvard.edu/abs/2016MNRAS.462.3180C, to select Very H=
igh Energy candidates for Imaging Atmospheric Cherenkov Telescopes (I=
ACTs) observation, from unclassified blazars listed in the LAT 4-year Point=
Source Catalog (3FGL)
We apply, as modification in the original B-FlaP algorithm, the va=
lue of the lower classification threshold (LHSP > 0.8), in orde=
r to increase the number of candidates, although decreasing a bit the preci=
sion (75%). However in this way, we improved the final result because the s=
ensitivity increases to ~ 15% and the misclassified fraction of non-H=
SP remains very low (~ 2%).
Applying the algorithm to BCU, we selected 52 sources as the most promis=
ing HSP candidates.
In order to obtain a cleaner selection of VHE candidates for direct IACT=
s observation we refined the HSP selection through additional parameters th=
at reproduce some peculiar characteristics of VHE sources as gamma-ray cand=
idates: spectral photon index < 1.6 and average significance over =
the 100 MeV to 300 GeV energy band larger than 4.0.
For each source of this clean list we compute the expected energy flux u=
sing the relation derived from fit model parameters included in the public =
XML Model File for LAT 4-year Point Source Catalog.
Paper is in progress and here we enclose a draft. This is likely to b=
e only a conference proceeding.
=
In Paper/ Tab.1 we report the full list of HSP candidates.
Paper/Tab.2 shows the clean list of HSP object identified as VHE candida=
tes for IACTs.
Table 2 data have been cross matched with 2WHSP http://www.asdc.=
asi.it/2whsp/ and 2FHL http://www.asdc.asi.it/fermi2fhl/ catalogs. 2FHL results confirm some, but not all, of these VHE cand=
idates. 6 of 16 listed sources in Tab.2 are in 2FHL too.=
p>
In Table 2 we marked these sources as VHT. However we consider the remai=
ning sources as interesting candidates that deserve particular attention in=
future IACT observing campaigns.

ors before any use of these data
