+## Managing Stage Discharge Curves
+
+Stage discharge curves are managed directly by editing the Workbench SQLite database. Open the database using your preferred database software such as [SQLite Studio](https://sqlitestudio.pl/), [DB Browser](https://sqlitebrowser.org/) or [DataGrip](https://www.jetbrains.com/datagrip).

 ## Analysis Bins
 
-Analysis bins represent the vertical bins that are used in the [binned sandbar analysis](/technical_reference/binned_analysis). They are editable and so the next time the sandbar analysis is performed it will include all the bins currently defined in the local database. Note that deleting an analysis bin will also delete the results for all historical sandbar analyses stored in the local database! Therefore, rather than deleting an analysis bin, it is recommended that you deactivate it by unchecking the checkbox on the properties form (see below).

+2. This new "merged" point dataset is converted to raster using [gdal_grid](https://gdal.org/programs/gdal_grid.html) with the same cell resolution as is used in the incremental and binned analyses.
+3. This raster is then clipped to the campsite areas using [gdal warp](https://gdal.org/programs/gdalwarp.html) with the digitized campsite polylines converted to polygons acting as the clipping mask.
+4. The area of each campsite is calculated for each elevation bin in much the same way as the regular binned analysis, albeit using [different bins](/Online_Help/Views/Managing-Reference-Information.html#campsite-analysis-bins) that are exclusively intended for the campsite analysis.
