Use `Shift-Tab` to see the optional variables that can be specified although a key format issue may be missing. A description of the data required by the `OBS` package (`flopy.mf6.ModflowUtlobs()`) can be found in the MODFLOW 6 [ReadTheDocs document](https://modflow6.readthedocs.io/en/latest/_mf6io/utl-obs.html). \n",
