CHANGELOG.md

All notable changes will be documented in this file

Unreleased

Changes currently on master, but not under a tag.

Changes

• The paths between imports where changed so that calls such as tupak.WaveformGenerator no longer work. Instead, we need to use tupak.gw.WaveformGenerator. This was done to keep things cleaner going forward (when, for example, there may be multiple wfg's).

[0.2.1] 2018-07-18

Added

• InterferometerStrainData now handles both time-domain and frequencu-domain data
• Adds documentation on setting data (https://monash.docs.ligo.org/tupak/transient-gw-data.html)
• Checkpointing for dynesty: the sampling will be checkpointed every 10 minutes (approximately) and can be resumed.
• Add functionality to plot multiple results in a corner plot, see tupak.core.result.plot_multiple().
• Likelihood evaluations are now saved along with the posteriors.
• Add functionality to sample in redshift and reconstruction of source frame masses.
• Add functionality to combine result objects.
• Enable initial values for emcee to be specified.

Changed

• Changed to using setuptools for installation.
• Clean up of real data handling: all data is now windowed with a 0.4s roll off (unless set otherwise) and low-pass filtered.
• Add explicit method to create a power spectral density from time-domain data
• Clean up of PowerSpectralDensity() - addds set_from methods to handle various ways to define the PSD.
• Clean up of detectors.py: adds an InterferometerStrainData to handle strain data and InterferometerSet to handle multiple interferometers. All data setting should primarily be done through the Interferometer.set_strain_data.. methods.
• Fix the comments and units of nfft and infft and general improvement to documentation of data.
• Fixed a bug in create_time_series
• Enable marginalisation over calibration uncertainty in Inteferemeter data.
• Fixed the normalisation of the marginalised GravtitationalWaveTransient likelihood.
• Fixed a bug in the detector response.
• Specifying detectors by name from the default command line options has been removed.
• The prior on polarisation phase has been reduced to [0, pi].
• More prior distributions added.
• More samplers supported, pymc3
• More core likelihoods, Poisson, Student's-t
• Add support for eccentric BBH
• Result print function fixed
• Add snr functions as methods of Interferometer

[0.2.0] 2018-06-17

First pip installable version https://pypi.org/project/TUPAK/ .

Added

• Reoriganisation of the directory into tupak.core and tupak.gw.
• Reading of frame files.
• Major effort to update all docstrings and add some documentation.
• Marginalized likelihoods.
• Examples of searches for gravitational waves from a Supernova and using a sine-Gaussian.
• A PriorSet to handle sets of priors and allows reading in from a standardised prior file (see https://monash.docs.ligo.org/tupak/prior.html).
• A standardised file for storing detector data.

Removed

• All chainconsumer dependency as this was causing issues.
