NH3 Laser data set (Santa Fe prediction competition)
This data set contains the output power of a
NH3 laser whose dynamics are associated with the Lorenz-Haken
equations [Haken, 1975]. This dataset was collected by Hubner et al.
The noise level is taken to be below the resolution of
an (8 bit) analogue to digital converter.
Laser data set
This data set contains data from a stroboscopic cross section
of the output power of a nuclear magnetic resonance
(NMR) laser operated at ETH Zurich [Flepp, 1991].
The lasing particles are Al atoms in a ruby
crystal, and the quality factor of the resonant structure
is modulated periodically. Output power of the laser is reflected in the
voltage across the antenna (thus allowing for negative values).
circuit data set
The data consists of a time series of voltages with a sampling time of 20
seconds. Each data point is stated to 3 digit accuracy and it is believed
that the observational uncertainty is dominated by truncation error at
this level. This dataset was collected by Abarbanel and Rulkov
(see [Rulkov, 1994] and [Abarbanel, 2000]).
Cardiac interval data sets reflecting the time intervals between
consecutive heart beats over a period of approximately 24 hours.

Note that this interbeat data was extracted using the program for
converting annotation files to RR intervals called
