gwcat-data

Data from LIGO-Virgo gravitational wave detections, built from Gravitational Wave Open Science Centre and GraceDB. For usage see gwcat.cardiffgravity.org

Data files (GWOSC + GraceDB):

• all data (JSON) (includes parameter definitions and referece links)
• all data (JSON, minified)) (includes parameter definitions and reference links)
• data values only (JSON))
• Data parameters only (JSON))
• References/links only (JSON))
• data values (CSV)
• Data parameters (CSV)
• References/Links (CSV)

Sky localisation images:

• Location: https://ligo.gravity.cf.ac.uk/~chris.north/gwcat-data/data/png/<filename>
• Filename formats for <event> (e.g. GW150914, S190510g etc.):
  • Mollweide: <event>_moll.png
    • (e.g. S191105e_moll.png)
  • Mollweide (rotated to centre on peak location): <event>_moll_rot.png
    • (e.g. S191105e_moll_rot.png)
  • Cartesian fullsky: <event>_cart.png
    • (e.g. S191105e_cart.png)
  • Cartesian fullsky (rotated to centre on peak location): <event>_cart_rot.png
    • (e.g. S191105e_cart_rot.png)
  • Cartesian zoomed onto peak location: <event>_cartzoom.png
    • (e.g. S191105e_cartzoom.png)
• “Pretty” versions of images (NB these are under development, and may change style)
  • Mollweide (white background): <event>_moll_pretty.png
    • (e.g. S191105e_moll_black.png)
  • Mollweide (black background): <event>_moll_pretty_black.png
    • (e.g. S191105e_moll_black.png)
  • Cartesian zoomed on peak location (no border): <event>_cartzoom_pretty.png
    • (e.g. S191105e_cartzoom_pretty.png)
• Thumnail of all images have .thumb.png extension
  • (e.g. S191105e_cartzoom.thumb.png)
• All images are in Equatorial (J2000) coordinates.
