ACR – Angle Correction for Rotators

Simple script to load data from a rotator and correct for common errors in a rotator setup.

Dependencies

• python
• numpy
• matplotlib

Prerequisites

• 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.

Usage

Run

python acr.py -i inputfile.dat -o outputfile.acr.dat
