========================== 
Methodological information
==========================

This data consists of the results of numerical simulations described in the
paper "Noise-free generation of bright matter-wave solitons", which are plotted
in Figures 2-5 of the paper.

Instruments, hardware and software used: Matlab, Python, xmds2
(http://www.xmds.org/)

Date(s) of data collection: 2018


=========================
Data-specific information
=========================
File names for .csv files correspond to the relevant parts of the figure and
the quantities plotted. For more information, see the description of the
figures in the paper.

Note that file Figure4ab.h5 contains space-time wavefunctions for many
realizations of TW trajectories. The hdf5 dataset is stored as real (phiR) and
imaginary (phiR) parts under the group "1". The dataset is indexed by space
("x"), time ("t") and realization index ("j"). Plotted in the figure are the
first realization (index 0) and the average (over j).

Note that file Figure4c.h5 contains in group "1" the following data in a
slightly different notation to the paper. The following datasets are indexed in
the file by time ("t"), gamma ("gamma") and atom number ("natoms"):

w_gp : Gross-Pitaevskii fitted width (\ell_{S, GP})

w_avg: Average fitted width over TW trajectories (\langle \ell_{S,i}
\rangle_{TW})

w_std: Standard deviation of the fitted width over TW trajectories (used to
construct shaded uncertainty areas)
