Access to LIGO/Virgo data¶
Users with LIGO.ORG
credentials are freely able to access all archived data either from local gravitational-wave frame files or over an NDS server. The gwdetchar.io.html
module is designed to simplify this process for scripting, and provides the following functions:
|
Check that a state flag is active during an entire analysis segment |
|
Find and remove channels from a given list that are not available in a given cache of frame files |
|
Retrieve data for given channels within a certain time range |
Note, in most cases, calls to gwdetchar.io.datafind.get_data()
that are unable to read from a local source will automatically fall back to NDS. For users who wish to run omega scans over publicly available data, please refer to gwdetchar.omega.config
.
For more information about data access, please see GWpy.
