Files included in this archive and the format of records within
them are as follows:

    bary_extrema.csv
    	Barycentre extrema (minima and maxima) sorted by distance
	from the centre of the Sun.  Fields in this file are:
	
	    1.	Distance from centre of the Sun in units of mean
	    	solar radii (696,000 km)
	    2.	Julian day
	    3.	Civil date and time, trailing letter indicates Julian
	    	or Gregorian calendar
		
    bary_minmax.csv
    	Barycentre minima, maxima, and crossings of the mean solar
	radius.  Fields are:
	
	    1.	Event type:
	    	    minG    Global minimum (closest approach to solar
		    	    centre between entry and exit of the Sun)
		    min     Local minimum
		    exit    Crossing from inside Sun to outside
		    max     Local maximum
		    maxG    Global maximum (furthest excursion from
		    	    solar centre between exit and entry of
			    the Sun)
		    entry   Crossing from outside Sun to inside		    
    	    2.	Distance from centre of the Sun in units of mean
	    	solar radii (696,000 km)
	    3.	Julian day
	    4.	Civil date and time, trailing letter indicates Julian
	    	or Gregorian calendar

    bary_local.csv
    	Chronological list of the number of minima and maxima between
	barycentre crossing of the solar radius.  Fields are:
	
	    1.  Number of minima/maxima
	    2.	Direction of first crossing, "enter" or "exit"
	    3.	Julian day of first crossing
	    4.  Civil date and time of first crossing
	    5.  Direction of second crossing, "enter" or "exit"
	    6.  Julian day of second crossing
	    7.	Civil date and time of second crossing
	    
    bary_local_hist.csv
    	Histogram of the number of barycentre minima and maxima between
	barycentre crossings.  Fields are:
	
	    1.  Number of minima/maxima
	    2.	Number of occurrences of this number of minima/maxima
