analyse(results: Results) → Results[source]

Method to analyse the results of the hanning smoothing operation.

prepare() → HanningResults[source]

Method where the hanning smoothing operation is executed.

The MS SPECTRAL_WINDOW table is examined to see if the SDM_NUM_BIN value is greater than 1. If the value is great than 1, then hanning smoothing does not proceed.

The CASA task hanningsmooth() is executed on the data, creating a temporary measurement set (MS). The original MS is removed from disk, and the temporary MS is renamed to the original MS. An exception in thrown if an error occurs.

Returns:: HanningResults() type object
