3.12.04Lessons from H.E.S.S. data of 2003/2004
- Hard spectra for most new TeV sources.
- Most skymaps (of galactic sources) are produced using Hard cuts (< 0.1°, image SIZE > 200 pe., >= 2 tels)
- Hard spectra motivates further efforts for E > 10 TeV detection
(Astrophysical motivations are clear and discussed this week)
Investigate
- HESS performance at E > 10 TeV at high zenith angles - New dedicated telescopes for E > 10 TeV astronomy

3.12.04
E < 0.6 TeV 0.6 < E < 1.4 E > 1.4 TeV
eg. the hard spectrum of RXJ1713 permits good statistics well above HESS threshold.
Images below have the same gamma excess (overall)
