Compiled M-dwarf photometry
A variety of photometry from the literature for M-dwarfs. All in ASCII machine readable form. Many of these tables were converted from the ADS scans of the papers for my own use, but are made available in case they are also useful to other researchers.
Monitor rotation period data
All the Monitor rotation periods that have been published so far are available here.



Transit model demo
Experimental interactive demonstration of transit models.
