How researchers see this paper

The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Optical gas sensing: a review (2012, methodology): “Public-domain quantified spectra are available from the US National Institute of Standards and Technology (NIST) [19] , Pacific Northwest National Laboratory (PNNL) [19] , and may be calculated using information in the Hitran database [20] .”
ExoMol line lists IV: The rotation-vibration spectrum of methane up to 1500 K (2014, background): “Comparison of the 10to10 and Sharpe et al. (2004) crosssections of 12CH4 at T = 50 C. energy levels, particularly at higher energies, and hence, the related transition frequencies could be improved.”
Exoplanet Biosignatures: A Review of Remotely Detectable Signs of Life (2017, methodology): “Figure 6 shows the line absorption intensities or absorption cross sections for the biosignature gases presented in this section for reference, drawing from the HITRAN 2012 (Rothman et al., 2013) and PNNL (Sharpe et al., 2004) spectral databases.”
The HITRAN 2008 molecular spectroscopic database (2005, methodology): “spectra from PNNL [314] much better than HITRAN2012.”
ExoMol: molecular line lists for exoplanet and other atmospheres (2012, background): “Currently the main source of methane spectra are HITRAN (Rothman et al. 2009), which is only really appropriate for temperatures below 300 K and is then still not complete, or the low-resolution PNNL database (Sharpe et al. 2004).”
