Bands 6 and 7 of Herschel's HIFI instrument suffer from a phase and amplitude shifting ripple that is dependent upon numerous receiver parameters. While one can attempt to fit a sinusoid to the ripple, this quickly becomes insufficient for a desirable signal to noise ratio. Extending upon a technique pioneered by Ronan Higgins, we have come up with a faster, more comprehensive way to reduce HEB baselines. We will demonstrate this technique using the data of the Herschel Inner Galaxy Gas Survey (HIGGS) project.
