sd.scantable.scale - Function

5.1.2 Scale spectra by the given factor
Description

Return a scan where all spectra are scaled by the given ’factor’. The factor can be a float or one- or two-dimensional float array. If it is one-dimensional array, the scaling will be done in channel-by-channel manner. If it is two-dimensional, the scaling will be done in element-by-element or row-by-row manner.

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.
