FREQUENCY RESOLVED ATLAS OF THE CONTINUOUS GRAVITATIONAL WAVE SKY

O3a data, 500-1000 Hz

The atlas is provided as files in Mapped Vector Library (MVL) format:

• All MVL files compressed (tar.gz) (33 GB), containing:
  • The main data set O3a_atlas.mvl (72 GB)
  • The summary data set O3a_atlas_summary.mvl (13 GB)
  • The spatial index O3a_spatial_index.mvl (51 GB)
• All examples (tar.gz)
• README
• A frequency resolved atlas of the sky in continuous gravitational waves, Vladimir Dergachev, Maria Alessandra Papa, Phys. Rev. X 13, 021020 (2023)
• GWPAW 2022 poster
• Data format description
• Also see Expanded atlas of gravitational waves covering 20-1500 Hz with larger tolerance for frequency drift (up to 5e-10 Hz/s)

The MVL files can be accessed either using C-level libMVL library, or using R package RMVL.

The plot at the top of the page was produced using visualize.R script included in the examples. We also provide examples that allow to explore atlas programmatically, see README for more details.

The mapped vector library format is optimized for use with solid state drives that allow random access to the data.

We also have MVL files for the Gaia DR3 data and Expanded atlas of gravitational waves.
