Presentation
        -----------------

        The paths are given for any total or annular solar eclipses visible from continental France from -2000 to 3000.
        For each eclipse one gives the location of the centrality line, the northern and southern boundaries and the duration of centrality.
        Eclipses have been selected if the shadow strip crosses continental France
        The data is given in a small ascii file.

Date     :    Date in dd/mm/yyyy format and in UT (Gregorian calendar since 15/10/1582)
Time     :    Time in hh:mm  in UT

Northern boundary  : Latitude and longitude in degrees
Line of centrality : Latitude and longitude in degrees
Southern boundary  : Latitude and longitude in degrees

Az_sun   :    Azimuth of the sun from the south toward east in degrees
h_sun    :    Altitude of the sun in degrees
axe_a    :    Semi-major axis of the shadow in km
axe_b    :    Semi-minor axis of the shadow in km
speed    :    Speed of the shadow motion on the Earth in km/s

• The difference between TDB and UT is quadratically extrapolated in the distant past or in the future from known values of TD - UT.
• Computations are based on lunar and solar theories developped at the Institut de Mécanique Céleste in Paris
• The ratio k between the moon and earth radius is taken as  0.2725076 (IAU recommended value)
