Example 2: A custom configuration
-------------------------------

__Working directory:__ `/path/to/nshmp-haz/etc/examples/2-custom-config`

Navigate to the directory above and execute the following:

```Shell
hazard ../../peer/models/Set1-Case1 "San Francisco,-122.40,37.75" config.json
```

In this example we've overridden the configuration supplied by the model. Specifically:

* The upper end of each hazard curve has been truncated at 3 standard deviations.
* Hazard curves have been saved as poisson probability instead of annual rate.
* Hazard curves have been calculated for 3 `imts` ([intensity measures](http://usgs.github.io/nshmp-haz/javadoc/index.html?org/opensha2/gmm/Imt.html), or spectral periods).
* The `imls` (intensity measure levels or x-values) of the resultant curves have been explicitely defined for each `imt`.

See the [configuration specification](https://github.com/usgs/nshmp-haz/wiki/Configuration) for details on default values and supported options and formats.
