2) - The photometric lightcurves as ascii files with one line for each photometric point 

     Contents: 
       - 282 observations of 98 events observed from 55 sites from june 
         1996 until november 1997
       - each light curve corresponding to each observation,
       - the light curves are provided in the files dXXXYYY.ZZZ where
	 XXX is the coded name of the site of observation on 3 characters,
	 YYY is the type of phenomena, aammjj,ZZZ is the date.
	 Example: dbor1e2.077 is Bordeaux(bor), 1e2 is J1 eclipse J2 and 077 Is July 7th
       - the file dXXXYYY.ZZZ.png provides the plot of the light curve


     Format:
      The lightcurves are provided in the files d.... with the following format,

      - first line : event, date, site of observation, number of points
      - second line: alpha, delta of jupiter at 0h, the julian data at 0h
                     and a parameter to indicate we are in magnitue 
		     alpha is counted in hours and decimal fraction
		     delta is counted in RADIANS
      - third line : longitude and latitude de of the observatory,
                     the longitude is counted in hours and decimal fraction 
                     counted positively towards WEST (format F10.6),
                     the latitude is counted in RADIANS counted positively 
                     towards north (format F9.7)
      - fourth line: KA,KX and sequante Z (KA and KX not used, sequante Z: inverse
                                           of cosine (zenithal distance) )
      - line 5 and next: hour minute second in UTC, magnitude drop (the last column 
        [.00000] is not used)
 
3) - the tables and figures of the paper describing the observations and published
     in Astronomy and Astrophysics:
       - zcatal97.tab4p1 to p9 .ps: tables 4 of the paper
       - zfich1 to 33 .ps: figures 1 to 33 of the paper
