 | `TAR1090_ENABLE_ACTUALRANGE`    | Set to `true` or leave unset to enable the outline of the actual range of your station on the map; set to `false` to disable the this outline | `true` (enabled) |
+| `TAR1090_AISCATCHER_SERVER` | If you want to show vessels from your AIS-Catcher instance on the map, put the URL of your AIS-Catcher or ShipFinder website in this parameter (incl. `https://`). Note - if you are using "barebones" AIS-Catcher you should add `GEOJSON on` after the `-N` parameter on the `AIS-Catcher` command line. If you use [docker-shipfinder](https://github.com/sdr-enthusiasts/docker-shipfinder), no change is needed for that container | Empty |
+| `TAR1090_AISCATCHER_REFRESH` | Refresh rate (in seconds) of reading vessels from your AIS-Catcher instance. Defaults to 15 (secs) if omitted | `15` |
