Figure 1:
Gaussian fits to the weak telluric O3 (
304, 26-303, 27) line
during the Odin observations of
determined the AOS channel of the line peak
(channel width = 0.32 km s-1). The adopted average channel values for the segments, during
which the phase lock was stable, are indicated (see the text).
Figure 2:
The submm NH3 (JK = 10-00) line (523.66 m) observed with Odin toward
(histogram).
At 572.5 GHz the Odin
-scale
is related to the flux density by
Jy/K.
The quadrupole hyperfine lines in their equilibrium ratios are indicated, together with their total contribution.
