Notes.

(a)

The fullwidth at half maximum (FWHM) of the telescope primary beam can be computed approximately as FWHMAPEX = 17.′′7 × (345/ [νobs/ GHz]), and FWHMIRAM = 10.′′7 × (230/ [νobs/ GHz]), where νobs is the observation frequency.

(b)

Main beam efficiency of the telescope. The main-beam brightness temperature is obtained as /ηMB.

(c)

Apperture efficiency of the telescope.

(d)

Inverse of the point source sensitivity of the telescope. The relation between antenna temperature and flux density is expressed as /Γ.
