• A CORRELATION BETWEEN STELLAR ACTIVITY AND HOT JUPITER EMISSION SPECTRA (2010, unknown): “We also include the sun in our table, with an average Lyman α flux of 5.6 × 10−6 times its bolometric flux (Woods et al. 2000; Wood et al. 2005) and a SHK value of 0.133 (Livingston et al. 2007).”
• Photochemistry and diffusion in Jupiter's stratosphere: Constraints from ISO observations and comparisons with other giant planets (2005, background): “These values represent moderate solar conditions [cf.

• Solar Irradiance Variability and Climate (2013, methodology): “Finally, the reconstructed irradiance in Ly-α agrees with the composite of measurements and proxy models by Woods et al. (2000) going back to 1947 (Krivova, Vieira & Solanki 2010).”
• Causes of low thermospheric density during the 2007–2009 solar minimum (2011, methodology): “7 generally reaches a plateau while solar EUV irradiance continues to exhibit small variations [e.g., Barth et al., 1990; Woods et al., 2000]; in 2008–2009, this plateau was slightly below the preceding minima, with an annual average for 2008 of 69, as compared to an annual average for 1996 of 72.”
• Solar EUV Experiment (SEE): Mission overview and first results (2005, methodology): “The solar rotation variation difference is primarily explained for the 121–122 nm comparison because the H I Lyman-a irradiance is known to have differences between the long-term and short-term variations relative to the Mg II C/W ratio [ Woods et al., 2000a ], whereas this UARS proxy model assumes ”
