SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires requests, and includes scripts (resource) components.

What problem does it solve?

GWOSC data access is scattered across catalogs, and performing searches, retrieving event parameters, and obtaining strain data typically requires navigating multiple endpoints. This Skill streamlines discovery, parameter extraction, and data retrieval from GWOSC through a unified script-driven workflow.

Core Features & Use Cases

  • Catalog discovery and event listing: list available GWOSC catalogs and fetch basic event metadata.
  • Event parameter access: retrieve detailed mass, distance, redshift, SNR, and detector information for selected events.
  • Strain data access: list available strain files per event and download selected data for analysis from detectors (H1, L1, V1) and durations (32s, 4096s).

Quick Start

Ask this skill to list catalogs, search for events by criteria, and download strain data for a chosen event.

Frequently Asked Questions about gwosc

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I download gravitational wave strain data from GWOSC for a specific event?

You can download gravitational wave strain data by searching for a specific event and selecting from available strain files. The Skill retrieves data from detectors like H1, L1, and V1 across durations such as 32s or 4096s.

Can I search GWOSC catalogs and filter events by mass, distance, or SNR?

Yes, you can list available GWOSC catalogs and filter events by mass, distance, or SNR. The Skill queries the GWOSC API to retrieve basic event metadata matching your specific search criteria.

What gravitational wave event parameters can I retrieve using the GWOSC API?

You can retrieve detailed event parameters including mass, distance, redshift, SNR, and detector information. The Skill accesses the GWOSC API to extract and print these parameters for selected events.

Do I need the requests library to access LIGO and Virgo data through this workflow?

Yes, the requests library is required to access the GWOSC API. The Skill uses requests to handle multiple catalogs, events, and strain formats when downloading LIGO and Virgo data.

What's the best way to list available GWOSC catalogs and their events?

The best way to list available GWOSC catalogs is to use this Skill's catalog discovery feature. It fetches basic event metadata directly from the GWOSC API, allowing you to quickly explore and select events.

Are there limitations when retrieving strain data from multiple detectors simultaneously?

The Skill handles multiple detectors and strain formats but prints concise results. You select specific strain files per event from available detectors (H1, L1, V1) and durations (32s, 4096s) to download for analysis.
