Fields in the transits.csv database are as follows:

    1.	Transit of  	Name of the planet (e.g. "Venus", "Mars")
    	    	    	transiting the Sun.
    2.	Visible from	Name of the planet from which the transit
    	    	    	is visible.
    3.	First	    	Julian day number of integration step when
    	    	    	transit first observed.
    4.	Maximum     	Julian day number of integration step when
    	    	    	transit reached maximum magnitude (planet
			closest to apparent centre of the solar disc).
    5.	Last	    	Julian day number of integration step when
    	    	    	transit last observed.
    6.	Solar radius	Mean radius of the Sun as seen from the
    	    	    	"Visible from" planet in degrees.
    7.	Depth	    	Angular distance, in degrees, of the
    	    	    	centre of the "Transit of" planet from
			the apparent centre of the solar disc at
			the "Maximum" time.  A perfectly central
			transit would have a "Depth" of zero,
			while a graze will have a "Depth" comparable
			to the "Solar Radius".
