The secular light curves presented here have been
accepted for publication in "Secular Light Curves of
Comets....",  Ferrìn, 2005, Icarus.   Two plots are needed
per comet, the Log plot, and the Time plot.  It helps to
read the above paper to facilitate the interpretation of
the plots and the many parameters measured from them.
        It is suggested to print first the
Key To Parameters of the Log Plot and then the
Key To Parameters of the Time Plot .   In particular Ron
and Roff are the turn on and turn off points of the light
curve.  Before Ron and after Roff, the comet is in the
nuclear phase, a bare nucleus.   There is also a listing
of values of Ron and Roff that may be useful to plan
nuclear observations.   It is also useful to print the new
version of the Parameters measured from the plots.   
New light curves will be uploaded as soon as they
are available.
