Introduction.  
=============
      In this document  you will  find what we believe is
the most complete  compilation of rotational periods and
peak to valley amplitudes (APTV) of the rotational light 
curves of comets.
      You are welcome to use this data set which has been
written in ASCII format for your convenience, so that it
can be transported easily. However we request, in accord
with scientific  principles,  to give  proper  credit to 
this  work:  

Ferrín, I., "Secular Light Curve of Comets,
II: 133P/Elst-Pizzarro, an Asteroidal Belt Comet", 2006,
ICARUS, in press.  Updated regularly at the web site:
http://www.webdelprofesor.ula.ve/ciencias/ferrin

    A preliminary analysis of this data has already been
carried out (above reference) with the following result:
there   is  a  correlation  of  rotational  periods  and 
diameters that may  be evidence of rotational evolution.
An histogram of number vs rotational period,  allows the
determination  of  a  rotational  error   for   snapshot 
observations, of  ±0.63  magnitudes.  The  histogram  is 
available elsewhere in this web page. 

      Please  contribute  to  this  effort by  making 
corrections and additions, or by sending new data.
