# object.prt

The **object.prt** file is commonly used to:

* Print daily channel outflow to compare to observed streamflow a stream gage
* Print daily flow to a file that can be read in as a point source from another SWAT+ simulation

The only timestep output can be printed at using this file is daily. A description of the output files is provided in the [SWAT+ Output Files](https://swatplus.gitbook.io/io-docs/swat+-output-files) section.
