    121 I calculated duty-cycle with a Sun zenith angle greater
    122 than 105 deg, which means that Sun must be at least 15 deg below
    123 horizon, and not with an angle of 115 deg. I tried this calculation also
    124 with a limit of 108 deg, because a lot of people assume that the
    125 astronomical sunset is when the Sun is 18 deg below horizon. Using this
    126 assumption the calculated duty-cycle decreases of about 4\%(from 1.225 to
    127 1.18 srad per year or from 9.75\% to 9.36\% vs 4pi srad per year). Anyway
    128 the definition of astronomical sunset influence the main cut on duty-cycle.
    129 About wind I can say that the data I used were provided by NOT, which is
    130 situated in a place more windy than where MAGIC is growing up. I made
    131 the calculation also with other upper limits to wind's speed then the
    132 usual 10 m/s, and we can gain quite a lot of duty-cycle (even about
    133 1.5\%more vs 4pi srad per year) so it should be interesting to test the
    134 telescope during some windy or foggy days.
