# readmeCompIPscatt

This folder contains the inseti files used for [1].

- Files with prefix `paperF` or `fresnel` inside use the real-world data from Institute Fresnel. How to get experimental data from Institute Fresnel is described in readRAWData.html.

- The inseti files with prefix `fineData` are used to prepare data with noise on a fine grid (to avoid the inverse crime). The reference to such files, e.g. in paper1default, with `seti.loadFmeas` is commented currently.

- Note that the file `paper5gridScale` includes `seti.nOut` from the result with `paper1default`.

Run

`paperRun` runs

- `paperRun2Dsynth`,
- `paperRun2Dfresnel` and
- `paperRun3D`.

Each of these routines run IPscatt with several inseti-files in this folder.
