Access of O3 Alternate Calibration Release via GWpy

Data Analysis

Hi all,

The example Python/GWPy command for accessing O3 alternate calibration data on the GWOSC webpage does not seem to work for me.

from gwpy.timeseries import TimeSeries
data = TimeSeries.fetch('H1:DCS-CALIB_STRAIN_CLEAN_C01_AR', start=1240559616, end=1240559626, host='nds.gwosc.org')

returns an error:

no data received from nds.gwosc.org for [1240559616 ... 1240559626)

This was definitely working for me around 6 months ago. Has something changed? Has the data been moved?

Thanks

Hi Tom,

I can confirm that I get the same result. I’ll look into it.

@tomkimpson Thank you for flagging this issue. It looks like the NDS2 server ‘nds.gwosc.org’ was in a bad state. We restarted the server, and it seems to be working now. Please try again, and let us know if you still are seeing error messages.
