Notes. (a)From CONCERTO Collaboration (2020).(b)Valid detectors are the LEKIDs that met the selection criteria in over 70% of the 44 Uranus photometric scans.(c)FWHM of the central Gaussian beam (2022). (d)FWHM of the Gaussian whose solid angle is equivalent to that of the beam (Ω)(e)Solid angle derived from the radial profile (2022). (f)Given for a Uranus spectral energy distribution. (g)Not taking into account the model uncertainty (which is estimated to be <2%, Planck Collaboration (2016)).(h)From COSMOS observations at a mean pwv of 0.81 mm and elevation of 56 degrees.
