14.1 Introduction

14.1.7 Radial velocity spectra

Radial velocity spectra are published for nearly one million sources. A few things to notice:

  • •

    The spectra are scaled to a continuum level of 1, but three different normalisation methods were used resulting in different levels, cf. Section 14.2.7;

  • •

    Spectra may occasionally show spikes due to noise at the edges, cf. Section 14.2.7;
