#
# The Mg II core-to-wing ratio is derived by taking the ratio of the h and
# k lines of the solar Mg II feature at 280 nm to the background or wings at
# approximately 278 nm and 282 nm. The h and k lines are variable chromospheric
# emissions while the background emissions are more stable. The result is a
# robust measure of chromospheric activity. This ratio has been shown to be
# a good measure of solar UV and EUV emissions.
#
# Each of the data sets was scaled to the original NOAA TIROS NOAA 9 data
# set with a linear fit of the overlapping data. The nature of the Mg II
# core-to-wing ratio and the quality of the data resulted in linear
# correlation coefficients between 0.98 and 0.999.
