Notes.
Schneider et al. (2003) quote smaller values for the area of the LWS beam at the same wavelengths than van den Ancker et al. (2000), which is likely due to the ISO-LWS beam profiles being significantly different in practice than expected, leading to changes to the quoted beam sizes in the LWS documentation over time. For example see the discussion presented by Liseau et al. (2006, Sect. 3.1). As such, the values presented by Schneider et al. (2003) are likely to be closer to the true LWS beam sizes.
