Un-normalised spectrum of β Peg around 817.0 cm-1. One full order and parts of two neighbouring orders on either side are presented. Three distinct water lines can be seen in the middle order. The non-linear form of the blaze function is indicated by the dashed line, which is a fifth order Legendre polynomial used to fit the continuum.
