Normalised spectrogram

This example shows a normalised spectrogram of the strain data from LIGO-Hanford around the time of GW150914.

gwpy-plot spectrogram \
    --gwosc \
    --ifo L1 \
    --start 1264315518 \
    --duration 1024 \
    --norm \
    --cmap Spectral_r \
    --imin .25 \
    --imax 4 \
    --interactive

The same command can be executed directly in Python as:

from gwpy.cli.gwpy_plot import main
main([
    'spectrogram',
    '--gwosc',
    '--ifo', 'L1',
    '--start', '1264315518',
    '--duration', '1024',
    '--norm',
    '--cmap', 'Spectral_r',
    '--imin', '.25',
    '--imax', '4',
    '--interactive',
])
