=============================================================================
These tables are based on the observed monthly mean sunspot numbers from
SILSO, Royal Observatory of Belgium, Brussels (sidc.oma.be/silso/home). The
observed values are smoothed using a 13 month running filter (the first and
last values have half weighting). Estimated values have an "e" suffix and
are calculated from observed monthly and predicted smoothed sunspot numbers.
Observed smoothed values precede the estimated values while predicted
smoothed values follow the estimated values.
The 10.7 cm solar radio flux values, including the "observed" values, are
obtained from sunspot numbers using a statistical conversion. They are
therefore described as "equivalent" solar radio flux values.
