There are at least two:
- the on-line GCVS has elements
- Doug Welch and Don Fernie have maintained cepheid databases for
quite some time. See
http://dogwood.physics.mcmaster.ca/Cepheid//HomePage.html
for links.
As with all light-curve elements, realize they are not terribly
accurate and if the epoch of maximum is old, you can have significant
changes.
