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.
