GEO600 Data for FRBs from SGR 1935+2154

Overview

Data used for the GW analysis in the paper: "A search for gravitational waves coincident with fast radio bursts from the magnetar SGR 1935+2154". The data are from the GEO600 detector, at times around 4 observed FRBs in the years 2020 and 2022. The data set contains 206543 seconds, or around 57 hours, of calibrated strain data.

Data Access

Single Computer Access

For work on a single computer, data may be accessed from a network data server (NDS2) using the NDS2 client or GWpy: 

from gwpy.timeseries import TimeSeries
data = TimeSeries.fetch('G1:DER_DATA_H', start=1272079196, end=1272079300, host='nds.gwosc.org')

For more examples of working with the NDS2 server, see the NDS2 Example Code.

Computer Cluster Access

For users of computer clusters, data jobs are available with HTCondor.

  • To set up OSDF anf HTCondor on your computer, see OSDF instructions.
  • If you are working on a computer cluster which already has access to LIGO/Virgo data, see accessing IGWN data.
  • Data gaps represent times when data are not available (e.g. the instrument was not running)
  • Data are under: osdf:///gwdata

To search for public data osdf file URLs, one may use gw_data_find for a given frame and segment interval: 


gw_data_find -r datafind.gwosc.org -o H -t H1_HOFT_C01_CLEAN_AR -s 1240559616 -e 1240559626 -u osdf

Alternatively, in python code, to download osdf url files for a given frame type and gps segment: 


import os 
import requests_pelican as rp 
from gwdatafind import find_urls

url = find_urls( "H", "H1_HOFT_C01_CLEAN_AR", 1240559616, 1240559626, urltype='osdf', host="https://datafind.gwosc.org")

with open(os.path.basename(url[0]), mode="wb") as file: 
    file.write(rp.get(url[0]).content)
