DATA & FILE OVERVIEW
--------------------

The file "Dataset.zip" contains data to generate Figures 1-5 from the main text. 

The data is prepared for each subplot of the figure and stored in ".txt" files.

The descriptions of most files consists of four parts:

Content: Name of the data and which Figure from the main context it is prepared for.

Description: A short description of the data.

Scaling or Units: For a 2D map, it gives the units as well as the file names of the axis data. If the file describes the units or one axis of a 1D plot, units are given directly.

Size: The dimension of the data is shown in the form of "row x column" and floating point numbers used are shown.


--------------------------
METHODOLOGICAL INFORMATION
--------------------------

The data was obtained through solving the general Gross-Pitaevskii equation coupled with reservoir rate equation (see main context) with split-step Fourier method. 

Computation language: C++ and CUDA.

Software to display the data shown on the paper: MATLAB.
