 ### Run Source Injection
 * Inject souces onto the L1 (detrended)
 * modify the corresponding ```config_injection.yaml``` file to configure all running options
 ```
     python ./injection_pipeline/injection_pipeline.py /path/to/config_injection.yaml

 ### Run L1 Detection & Photometry pipeline
 * Re-detect and redo the photometry measurements on the injected images
 * modify the corresponding ```config_photometry.yaml``` file to configure all running options
 ```
