Simple script to load data from a rotator and correct for common errors in a rotator setup.
python
numpy
matplotlib
- Rotation should be performed at otherwise stable conditions.
- Only one rotation per file
- To correct for backlash a forward and backward rotation has to be performed.
- To correct for slip ideally at least a 360° rotation has to be performed
- To correct for an initial phase in a meaningful way, you have a look at your sample when installing it.
Run
python acr.py -i inputfile.dat -o outputfile.acr.dat
You will get a window like this: Then adjust your parameters in the GUI. Use this at your own risk and check the contents of the script beforehand.
