This is a README file for the dataset "ULTRACONTROL.zip".

The dataset contains the MATLAB program code and input files to compute the deviation of a solar sail 
from a Halo orbit using Dynamical System Theory semi-analytically and their output file. 
These were developed and implemented by M. Nakamiya and C. McInnes 
under the funding from the European Unionfs Horizon 2020 research and innovation program 
under the Marie Curie grant agreement No 799873, from Sep 2019 to Aug 2021.
The details are as follows.
