        (year of discovery image), Comet designation (letter = half-month of

        SOHO comet number (internal numbering system which is numbered in the 
        order of discovery), year of perihelion passage, month of perihelion  
        passage, date of perihelion passage, perihelion distance, q (AU),     
        eccentricity, argument of perihelion (degrees), longitude of the      
        ascending node (degrees), inclination (degrees), group membership of  
        the comet (if any), Was the comet seen in the C2 telescope? (yes or   
        no), Was the comet seen in the C3 telescope? (yes or no), comet
