    Pyodine: an open, flexible reduction software for iodine-calibrated precise radial velocities
    Context. Many telescopes use an iodine (I 2) absorption cell to measure precise radial velocities (RVs), but their data reduction pipelines are all tailored to...

    Qualitative Interpretation of Galaxy Spectra
    We describe a simple step-by-step guide to qualitative interpretation of galaxy spectra. Rather than an alternative to existing automated tools, it is put...

    Quantifying the evidence for resonant damping of coronal waves with foot-point wave power asymmetry
    We use Coronal Multi-channel Polarimeter (CoMP) observations of propagating waves in the solar corona together with Bayesian analysis to assess the evidence of...
