Tau(225 GHz) = 1.088 (Click here to see a fit to this measurement)

Spectral Line Frequency (GHz) Opacity
12CO J=2-1230 1.52
12CO J=3-2345 3.70
12CO J=4-3460 12.19
[C I]809 20.13

Note: The scaling factors are now derived from actual skydips in the given bands. We use a tau and frequency averaged constant for each band. The old numbers (before February, 25th, 1999 were theoretical numbers calculated from atmospheric models. We do not show 492 and 691 GHz numbers because we do not yet have enough data points to calculate the factors.
