*TW 12/10/23*
- [Issue [111](https://github.com/TeamLEGWORK/LEGWORK/issues/111)] Allow `plot_sources_on_sc` to change the underlying sensitivity curve directly with `sc_vis_settings`

*TW 13/04/23*
- [Issue [109](https://github.com/TeamLEGWORK/LEGWORK/issues/109)] Upgrade `numpy` version
- Upgrade required to avoid error in `np.nan_to_num` usage - thanks to Jakob Stegmann for raising this

*TW 27/09/22*
- Change positions coordinate system to barycentric rather than heliocentric
- Ensure `theta` is a co-latitude in `amplitude_modulation`

*TW 14/09/22*
- [Issues [106](https://github.com/TeamLEGWORK/LEGWORK/issues/106)] Fix sampling of inclination and polarisation when they are not supplied to `Source`

*TW 27/06/22*
- [Issues [102](https://github.com/TeamLEGWORK/LEGWORK/issues/102)] Make SNR functions notice when you change confusion noise
- `Source.get_snr()` now takes all `sc_params` as arguments for re-interpolation etc
- `Source.get_snr_stationary` and `Source.get_snr_evolving` have the same parameters added as above
- All functions in `snr` now take `**kwargs` that are passed directly to `psd.power_spectral_density` for maximum flexibility

*TW 27/07/22*
- [Issues [101](https://github.com/TeamLEGWORK/LEGWORK/issues/101)] Unhide cells that change plot styles in demos so no errors are thrown
