sd.scantable.opacity  Function
5.1.2 Apply an opacity correction
Description
Apply an opacity correction. The data and Tsys are multiplied by the
correction factor.
Correction includes an elevation dependence of the opacity. Actual correction factor is exp(τ * ZD), where ZD is the zenithdistance and τ is a value given as the tau argument. If a list of opacities is provided, it has to be of length nIF, nIF*nPol or 1 and in order of IF/POL, e.g. [opif0pol0, opif0pol1, opif1pol0 ...]. If tau is ‘None‘ the opacities are determined from a model.
If insitu is True, or insitu is None and sd.rcParams[’insitu’] is True, the method will not return the result, but apply operation on this scantable.
