DESCRIPTION:
Updated solar irradiance reconstruction. (See also Lean et al., 1995).
Included are time series of annual mean irradiance from 1610 to 2000
of just the 11 year solar irradiance cycle, plus the 11 year
cycle with a background component. See Lean (2000) for discussion of
the amplitude of the background component.
