An object of the python class (defined in tube_calib_fit_param.py) holds the parameters needed for fitting the positions of the peaks formed by the slits or edges. The constructor has the following arguments:
| Order | Name | Type | Default | Description |
|---|---|---|---|---|
| 1 | Peaks | Array of real numbers | Mandatory | The expected positions of the peaks in pixels |
| 2 | Height | real number | 1000.0 | Expected height of peak |
| 3 | Width | real number | 30.0 | Expected width of peak in pixels |
| 4 | ThreePointMethod | boolean | False | If true, then the Three Point Method for MERLIN is used, else it's peak fitting of slits |
After creation it just needs to be passed to getCalibration of :ref:`Tube_calib`.
If ThreePointMethod is True, then the other arguments are ignored and Peaks can be an empty array.
