    LAL incompatibility

    As of today, the latest version of LAL in master does not jive well with GWpy. It seems that from lal import lal doesn't work anymore (although import lal does). For instance:

>>> data = TimeSeries.read("/archive/frames/trend/minute-trend/40m/C-M-11/C-M-1111554000-3600.gwf", "C1:LSC-DARM_OUT_DQ.mean")

  • Using numpy's truth methods with timeseries

    Using numpy's truth methods with timeseries

    I'd like to get a truthiness array for my timeseries. Since numpy is used to store the underlying data, I figured I could use np.where, but it's not working. It seems like astropy is causing the trouble:

    >>> np.where(data > 20)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/astropy/units/quantity.py", line 408, in __array_prepare__
    .format(function.__name__))
astropy.units.core.UnitsError: Can only apply 'greater' function to dimensionless quantities when other argument is not a quantity (unless the latter is all zero/infinity/nan)

    (data is a TimeSeries) I can get around this by casting to an np.ndarray:

    data = np.array(data)

    ...but I'd rather not have to do this (to preserve units and other metadata). Is there a way to get access to the underlying data without this astropy error?

    Make interpolated Q-transform spectrograms single precision

    This pull request ensures that interpolated Q-transform spectrograms are populated with single-precision floats, to save memory. It also slightly expands unit tests for the Q-transform, and fixes one of the documentation examples to use outseg rather than crop.

    This fixes #1050.

  • Refactor TimeSeries.q_transform() to support eventgrams

    Refactor TimeSeries.q_transform() to support eventgrams

    This PR substantially refactors TimeSeries.q_transform() to support eventgrams, a feature ported over from gwdetchar-omega. To simplify review, here is a summary of changes made:

    New Features

    • Introduce a new object class, ~gwpy.signal.qtransform.QGram, to support eventgrams
    • Introduce a new function, ~gwpy.signal.qtransform.q_scan(), which identifies the time-frequency plane at fixed Q with the most significant tile within a given (optional) search window. This method returns an instance of QGram along with the estimated false alarm rate from white Gaussian noise.
    • Include a method, QGram.table(), which converts a populated QGram object to an EventTable so that it can be rendered with matplotlib. Table columns are 'time', 'duration', 'frequency', 'bandwidth', and 'energy'. The only argument is an SNR threshold, which selects for tiles with energy greater than or equal snrthresh**2/2.
    • Introduce a TimeSeries.q_gram method to wrap around QGram.table.
    • Add a mismatch argument for q_scan() and TimeSeries.q_transform().
    • Add a unit test for the QGram object under gwpy/signal/tests/test_qtransform.py.
    • Add an example for the docs under examples/signal/qscan.py.

    Refactor Existing Features

    • Refactor spectrogram interpolation into ~gwpy.signal.qtransform.QGram.interpolate(). This reduces the cyclomatic complexity of TimeSeries.q_transform() to a level acceptable to CodeClimate.

    This fixes #922 and fixes #995.

  • Refactor gwpy.astro to depend on inspiral-range

    Refactor gwpy.astro to depend on inspiral-range

    This PR fixes #1248 by refactoring the gwpy.astro submodule so that it depends on the new inspiral-range Python package. As a result, the inspiral_range and inspiral_range_psd methods now fully account for cosmological corrections, while the SenseMon method has been refactored into corresponding functions sensemon_range and sensemon_range_psd.

    Things to note:

    • The inspiral-range package does not (appear to) support sensitivity metrics based on transient burst sources, so that functionality remains untouched
    • Where possible, I have tried to include references to the inspiral-range package as well as the paper (Belczynski et al. 2014) that lays out the cosmology-corrected range calculation
    • This PR also includes a number of smaller changes that do not affect overall functionality

    Closes #1292.

  • New whitening scheme based on inverse spectrum truncation

    New whitening scheme based on inverse spectrum truncation

    This pull request addresses a common issue with filter transients in the current whitening method by replacing it with an alternative scheme which designs and applies an FIR (finite impulse response) filter using inverse spectrum truncation.

    Other new features added include:

    • A method FrequencySeries.interpolate() and functions timeseries._fft_length_default, signal.filter_design.truncate_transfer, and signal.filter_design.truncate_impulse, all used to design the FIR filter
    • New keyword arguments for filter duration (in the time domain) and highpass corner frequency
    • In TimeSeries.whiten(), a default value of fftlengthwhich causes it to be set to max(2, int(2048 // self.sample_rate.decompose().value))
    • Automatic cropping of the beginning and end of the whitened timeseries by a segment of length filter_duration
    • Updates to the documentation for TimeSeries.whiten() addressing these changes
    • Updates to q_transform() that address these recent changes, including a new default fftlength that mirrors the one for TimeSeries.whiten
    • Unit tests for new functionality, a unit test for signal.window.planck(), and a bug fix in the unit test for FrequencySeries.inject()

    Note, these changes make it so that a simple call to TimeSeries.whiten() with no other arguments returns something sensible in most cases. It is also backwards compatible.

    This fixes #867. It is also related to #358 and #451.
