gw.download_strain_data.estimate_single_psd

gw.download_strain_data.estimate_single_psd(
    time_start,
    time_segment,
    window,
    f_s=4096,
    num_segments=128,
    det=None,
    channel=None,
)

Download strain data and generate a PSD based on these. Use num_segments of length time_segment, starting at GPS time time_start. If no channel is specified, GWOSC is used to download the data.

Parameters

Name	Type	Description	Default
time_start		start GPS time for PSD estimation	required
time_segment		time for a single segment for PSD information, in seconds	required
window		Window used for PSD generation, needs to be the same as used for Fourier transform of event strain data. Either provided directly as np.ndarray, or as dict in which case the window is generated by window = dingo.gw.gwutils.get_window(**window).	required
num_segments	int	number of segments used for PSD generation	`128`
det		If provided, will download data from GWOSC using TimeSeries.fetch_open_data(). Mutually exclusive with ‘channel’.	`None`
channel		If provided, will download the data from the channel instead of gwosc using TimeSeries.get()	`None`

Returns

Name	Type	Description
psd	np.array	array of psd
