Observations needed for best chances of detectability of the sources according to the modelled broadband SED.

CTAO detectability

5BZBJ1253+3826 ≥100 h No CTAO-N
5BZBJ1636−1248 50h ≥100 h CTAO-N
5BZBJ1251−2958 50 h ≥100 h Both
5BZBJ0040−2719 50 h No both
5BZBJ1302+5056 No No CTAO-N
5BZBJ1057+2303 50 h ≥100 h Both
5BZBJ2217−3106 No No CTAO-S
5BZBJ0124+0918 No No Both
5BZBJ1258+0134 ≥100 h No Both

Notes. The detectability was assessed visually by comparing the fluxes reached by the model with the CTAO-N or CTAO-S sensitivity. We assumed that a target is visible by an array if during the year it reaches an altitude higher than 30° above the horizon at its site declination.
