We start by deriving the sky temperature with:
|
(52) |
Estimating
requires knowledge of the forward efficiency
. It is also used to compute the sky emission
:
|
(53) |
The water vapor content variable of an atmospheric model predicting
sky brightness (
and
) and opacity
(
and
) in the signal and image sideband
is then varied in order to minimize the following quantity:
|
(54) |
The system temperatures for the signal
and image
sidebands are then computed as follows:
|
|
|
