## Description

```text
This instrument is a unit test for the source components.

The following sources are handled:
Source_gaussian SRC=0 (with gauss=0)
Source_gaussian SRC=1
Source_pt       SRC=2
Source_pt       SRC=3
Source_flat     SRC=4
Source_flat     SRC=5
Source_div      SRC=6
Source_div      SRC=7
```
