Rocking Curves
==============

For each pixel of the detector frames, fit rocking curves as Gaussian peaks.

**Inputs**: Dataset

**Outputs**: Dataset

Usage

Rocking Curve for one pixel
---------------------------

Click on any pixel in the left plot to inspect its rocking curve.

You can visualize the data for that pixel in motors space and the proposed fit.


**Axes selection** allows you to choose a different projection to visualize data.

Rocking Curve for the whole dataset
-----------------------------------

Click **Fit dataset** to fit Rocking Curve for the whole dataset.

Result is shown as maps. You can navigate between maps with **map selection** combobox.

Data can also be saved as hdf5 with **export maps** button at the end of the processing.

.. hint::
    In hdf5 file, when multi-peaks are fitted, the first dimension of each map represent the "peak index".
    Peaks are sorted from highest amplitude to lowest amplitude.

Common parameters
-----------------


- **Intensity threshold** is the bottom threshold to detect a peak. If all data is under this threshold, pixel is skipped.

- **Maximum Peak Count** sets the maximum number of peaks the algorithm can detect for each pixel.
