Summary

Passes the data to welch and returns a function that maps frequencies to ASD

Signature

def data_to_asdfunc(strains, mask, fs, chunktime_psd = params.DEF_CHUNKTIME_PSD, fmax = params.FMAX_PSD, average = 'median', line_id_ver = 'old')

Input variables

Name	Type	Default	Description
strains			Array with strains
mask			Boolean quality mask on strain data at 1 Hz
fs			Sampling frequency (Hz)
chunktime_psd		params.DEF_CHUNKTIME_PSD	Chunktime for PSD estimation
fmax		params.FMAX_PSD	Maximum frequency to estimate the PSD at
average		‘median’	Averaging method to use
line_id_ver		‘old’	Flag to use old or new version of line-identification code

Output variables

Return annotation	Docstring type	Description
None		Array with frequencies (Hz) 2. Array with PSD (Hz^-1) 3. Function mapping frequencies to ASD 4. Crude mask on frequencies with lines marked with zeros 5. Mask on frequencies with loud lines marked with zeros
