Bilby

Added
- Option for the GraceDB service URL
- Precessing BNS
- Functionality to make a waveform plot

Changed
- Changes to ROQ weight generation: finer time-steps and fixed a bug in the time definition
- Fixed typo "CompactBinaryCoalesnce" -> "CompactBinaryCoalescence" (old class now has deprecation warning)
- Fixed a minor bug in the frequency mask caching
- Minor refractoring of the GWT likelihood and detector tests
- Initial samples in dynesty now generated from the constrained prior

Added
- A plot_skymap method to the CBCResult object based on ligo.skymap
- A plot_calibration_posterior method to the CBCResult object
- Method to merge results

Changed
- Significant refactoring of detector module: this should be backward conmpatible. This work was done to break the large detector.py file into smaller, more manageable chunks.
- The `periodic_boundary` option to the prior classes has been changed to `boundary`.
*This breaks backward compatibility*.
The options to `boundary` are `{'periodic', 'reflective', None}`.
Periodic boundaries are supported as before.
Reflective boundaries are supported in `dynesty` and `cpnest`.
- Minor speed improvements by caching intermediate steps
- Added state plotting for dynesty. Use `check_point_plot=True` in the `run_sampler`
function to create trace plots during the dynesty checkpoints
- Dynesty now prints the progress to STDOUT rather than STDERR
- `detector` module refactored into subpackage. Maintains backward compatibility.
- Specifying alternative frequency bounds for the ROQ now possible if the appropriate
`params.dat` file is passed.

Removed
- Obsolete (and potentially incorrect) plot_skymap methods from gw.utils

Added
- Calibration method and plotting
- Multivariate Gaussian prior
- Bayesian model diminsionality calculator
- Dynamic dynesty (note: this is in an alpha stage)
- Waveform caching

Changes
- Fixed bugs in the ROQ time resolution
- Fixed bugs in the gracedb wrapper-method
- Improvements to the pp-plot method
- Improved checkpointing for emcee/ptemcee
- Various perforance-related improvements

Added
- Infrastucture for custom jump proposals (cpnest-only)
- Evidence uncertainty estimate to cpnest

Changed
- Bug fix to close figures after creation
- Improved the frequency-mask to entirely remove values outside the mask rather
than simply set them to zero
- Fix problem with Prior prob and ln_prob if passing multiple samples
- Improved cpnest prior sampling

Removed
-

Added
- Constraint prior: in prior files you can now add option of a constraint based
on other parameters. Currently implements mass-constraints only.
- Grid likelihood: module to evaluate the likelihood on a grid

Changed
- The GWTransientLikelihood no longer returns -inf for m2 > m1. It will evaluate
the likelihood as-is. To implement the constraint, use the Constraint priors.

Added
- Fermi-Dirac and SymmetricLogUniform prior distributions
- Multivariate Gaussian example and BNS example
- Added standard GWOSC channel names
- Initial work on a fake sampler for testing
- Option for aligned spins
- Results file command line interface
- Full reconstruction of marginalized parameters

Changed
- Fixed scheduled tests and simplify testing environment
- JSON result files can now be gzipped
- Reduced ROQ memory usage
- Default checkpointing in cpnest
