This vignette demonstrates how to plot the ARTSS1–5 X-ray source catalog in galactic coordinates.

The dataset artss15 is included in the package in a preprocessed form for reproducibility. It is based on the CDS/VizieR catalog J/A+A/687/A183 (bibcode: 2024A&A...687A.183S).

Main variables used below: - l, b: galactic longitude and latitude (degrees) - flux: X-ray flux (erg/s/cm^2)

In the plot, point color represents log10(flux).

ggplot(artss15, aes(l, b, color = log10(flux))) +
