Abstract:
A list of the 2027 stars that have the largest photometric amplitudes
in Hipparcos Photometry shows that the most variables stars are all
Miras. The percentage of variable types change as a function of
amplitude. This compilation should also be of value to photometrists
looking for relatively unstudied, but large amplitude stars.

History:
* 24-Aug-2002: about 60 wrong "Other names" were corrected at CDS,
in agreement with Saul J. Adelman; the actual number of stars is
2026, not 2027 as stated in the Abstract.
