The sample includes several unidentified Fermi-Large Area Telescope (LAT) sources (located at high Galactic latitude) as well as all the sources from the second Fermi-LAT catalog that are contained within the field of view of the VERITAS observations. The observations constitute a total live-time of ∼570 hr. In this work, we present the analysis results of a sample of 114 undetected objects.
