DOIAbstract
We present results from multiwavelength observations of the BL Lacertae object 1ES 1741 + 196, including results in the very high energy γ-ray regime using the Very Energetic Radiation Imaging Telescope Array System (VERITAS). The VERITAS time-averaged spectrum, measured above 180 GeV, is well modelled by a power law with a spectral index of 2.7 ± 0.7$_{stat}$ ± 0.2syst. The integral flux above 180 GeV is (3.9 ± 0.8$_{stat}$ ± 1.0$_{syst}$) × 10$^{−8}$ m$^{−2}$ s$^{−1}$, corresponding to 1.6 per cent of the Crab nebula flux on average. The multiwavelength spectral energy distribution of the source suggests that 1ES 1741+196 is an extreme-high-frequency-peaked BL Lacertae object. The observations analysed in this paper extend over a period o...
