The IDL template shown in source 1 is a minimal skeleton for a new tool. For more sophisticated applications, additional functionality must be implemented. In this case, a user should take a closer look at the available source code. The template covers only the implementation of a simple tool. For example, the PSF star tool is based completely on this template.

RETURN, 1 END PRO <MYTOOL>::InitObject, obj, x, y self-><SUPERCLASS>::InitObject, obj, x, y ; object specific extensions ...

| Placeholder | Description |
|---|---|
| <MYTOOL> | The IDL class name of the tool (CLASS element in the configuration file, for example ldrsPSFTOOL). |
| <SUPERCLASS> | (for example ldrsAREATOOL) |
| <MYTITLE> | The dialog title (for example Psf). |
| <MYCFG> | The place in the parameter file (for example PSFSTAR). |
| <MYOBJCLASS> | The tool specific graphic object (for example ldrsPSFSTAR). |
| <MYPREFIX> | The prefix used in the graphical representation (for example Psf ) |
Each tool is described in a section of the configuration file ldrs.cfg (see source 2). These sections must follow the subsequent rules:
| TOOL4.TAG = "targetBox" TOOL4.LABEL = "Target" TOOL4.CLASS = "ldrsTARGETTOOL" TOOL4.BM1 = "........................" TOOL4.BM2 = ".**.**.**.**.**.**.**.*." TOOL4.BM3 = "......................*." TOOL4.BM4 = ".........******.......*." TOOL4.BM5 = ".*.....**......*........" TOOL4.BM6 = ".*....*.........*.....*." TOOL4.BM7 = ".................*....*." TOOL4.BM8 = ".*...............*......"
