Notes. Mean surface pressure and temperature are from the v5.2 Mars climate database averaged over the field of view (http://www-mars.lmd.jussieu.fr). Standard deviation is provided to indicate the modeled variability within the sampled beam. Geocentric velocity from SOFIA’s observing coordinates (42N, 123W). The continuum emissions at 63 μm are understood to originate up to several wavelengths below the surface, therefore, the brightness temperatures are expected to be lower than the surface temperatures). The ΔRA and ΔDec represent the beam center pointing offset with respect to the disk center.
