Very High Energy Gamma-ray spectral properties of Mrk 501 from CAT Cerenkov telescope observations in 1997
A. Djannati-Atai, F. Piron, A. Barrau +31
The BL Lac object Mrk 501 went into a very high state of activity during 1997, both in VHE gamma-rays and X-rays. We present here results from observations at energies above 250 Ge…

Spectrum and Variability of Mrk501 as observed by the CAT Imaging Telescope
A. Barrau, R. Bazer-Bachi, H. Cabot +33
The CAT Imaging Telescope has observed the BL Lac object Markarian 501 between March and August 1997. We report here on the variability over this time including several large flare…
