Sourcespec

- HTML reports
- Option to provide station-specific spectral windowing

- Use `python-versioneer` to manage version numbers

- Bug fixes:
- Accept band code `C` for broadband seismometers sampled at >=250 Hz
- Require `cartopy>=0.18` for compatibility with `matplotlib>=3.3`

- Simplification of time window parameters:
- an unique window length, `win_length`, is used for time-domain S/N ratio
calculation and spectral analysis
- the old parameters, `noise_win_length` and `s_win_length`, are no more
supported and generate an error
- Reorganized config file and improved inline documentation within the file
- removed unused option: `fc_0`
- removed `pre_filt` option
- post-processing check on `fc` bounds has been removed
- Option to specify non standard instrument codes (e.g., `L` for
acceleration)
- Option to specify filter frequencies for local magnitude computation
- Plotting improvements:
- Show S/N ratio on trace plots
- Show spectral S/N ratio on spectrum plots
- Option to show/hide ignored traces/spectra (low S/N)
- Bug fixes:
- Pay attention to location code when building average spectra
- Plotting: avoid overlapping traces with different location code
- Plotting: avoid overlapping spectra with different location code

- Support for QuakeML input and StationXML
- Support for Python 3.5
- Only compatible with ObsPy >= 1.1.0
- Project reorganization:
- Project renamed to SourceSpec
- `ssp_residuals` renamed to `source_residuals`
- New installable package (e.g., via `pip`)
- Spectra are smoothed in log-freq (no more Konno-Ohmachi)
- Inversion is performed in a log-freq space
- Option to invert for `t_star_0` on the plateau level
- Traces are filtered before computing S/N ratio
- Trace clipping detection
- Traces are always plotted, even if no inversion is performed
- Use by default a global model for theoretical travel time calculation
- Possibility of using NonLinLoc travel time grids (requires `nllgrid`)
- New options for P and S arrival time tolerance
- New option for maximum epicentral distance for trace processing
- Possibility of using a NonLinLoc model grid for obtaining vs at the source
and at the receiver (requires `nllgrid`)
- Use `log10` of weighting function, since the inversion is done in magnitude
units
- Use `json` format for `traceid` correction file
- Save config file to output dir (only for `source_spec`)
- Save run completion time into output file
- Logarithmic average and logarithmic (asymmetric) error bars for Mo, fc and
source radius
- Computation of radiated energy
- Station-specific filters
- New parameters: `gap_max`, `overlap_max`
- Add legend to spectral plots
- Add event information, code version and run completion time to plots
- Multifigure plotting for traces and spectra (for large number of stations)
- New option to plot a station map, color-coded by station magnitude
(requires Cartopy)
- Refactoring of local magnitude computation code:
- Wood-Anderson amplitude is computed from the whole trace converted to W-A
and not converting only the min and max peaks (which is the default in
ObsPy)
- Trace windowing is computed on HF envelopes
- New option for custom Ml coefficients
- Remove unnecessary Ml options
- Code cleaning and optimization:
- Switch from `optparse` (deprecated) to `argparse`
- Code style fixes and refactoring
- New option to update a config file from previous versions
- BUGFIX: Fix a major bug in reading hypo pick file
- BUGFIX: Fix for pick file not read in `source_model`

- Trace plot showing S and noise time windows
- Improved handling of paz files
- Per-station Mo on output file
- Code cleaning and optimization
