sdpolaverage – Average SD spectra over polarisation – single dish task

Description

The task sdpolaverage exports data averaged over different polarisations. Scope of this task is to obtain Stokes I from orthogonal autocorrelation pairs (XXYY/LLRR). Available options include:

‘’ (blank string as the default: polarisation averaging turned off)
