This folder contains ASCII for the data plotted in the accepted manuscript 
Leonie Woodland, Ryutaro Okuma, J. Ross Stewart, Christian Balz and Radu Coldea, From continuum excitations to sharp magnons via transverse magnetic field
in the spin-1/2 Ising-like triangular lattice antiferromagnet Na2BaCo(PO4)2 
Physical Review B (in press) 2025.

This folder contains ASCII files for the (x,y,error) data plotted in Figs. 2a, 5a, 5b, 7a, 7a (inset), 7b, 7c, 9c, 14a, 14b, 14c and 17c
and (x,y) fits/calculations plotted in Figs. 2a, 4a, 4b, 6b, 6d, 6f, 6h, 6j, 6l, 7a, 7b, 7c, 9a, 16, 17b and 17c
and the intensity colour maps in Figs. 4a, 4b, 6a, 6b, 6c, 6d, 6e, 6f, 6g, 6h, 6i, 6j, 6k, 6l, 8a, 8b, 8c, 8d, 
	8e, 8f, 8g, 8h, 8i, 8j, 8k, 8l, 9b, 10a, 10b, 10c, 10d, 10e, 10f, 16, 17a and 17b.

The folder also contains (x,y) data - BZ.xy - to plot the Brillouin zone boundaries in the hk plane and 
an RGB colour map in colmap.dat.

All supplied data have had an estimate of the non-magnetic background subtracted off, except those for Figs. 10 and 17, as described in the text.

The supplied MATLAB code plot_data.m plots 50 figures when run in the same directory as the unzipped data files.
This usually takes about a minute (but can take up to 3 mins or longer) to run. Each figure panel in the paper is displayed in a separate matlab figure window, 
with the paper figure panel number, i.e. 4a to 17c, displayed in the figure window top banner. 
One can also run separate sections of the code for each individual figure.

(x,y,error) data : data points with errors
++++++++++++++++++++++++++++++++++++++++++++++
Energies are given in meV for modes ordered in increasing energy (unless otherwise stated), and (h,k,l) in rlu. 
Where applicable, wavevectors are given in Cartesian coordinates (x,y) where x corresponds to (x,-0.5x,0) and y corresponds to (0,-y,0) in r.l.u.
Intensities are given in arbitrary units. 
Magnetic fields are given in T.
The data for both Figs. 5a and 5b are contained in the file fig5.xye. 
In fig7b.xye and fig9c.xye, NaN values are used in some places as different bin widths were used at different fields, so there are not defined intensity values at the same energy values at all fields.

                        ModeNumber==4 is 3.5T//c taken from Fig. 4B of Ref. [14] and was extracted by eye, so the error is an estimate.

Colour map figures
++++++++++++++++++++++++++++++++++++++++++++++
The first row of the file gives the dimensions of the plot arrays in the form [nRows, nCols].

The intensities are smoothed between neighboring bins by convolving a matrix with relative weights 
A=[0.1  0.2  0.1; 0.2  0.8  0.2; 0.1  0.2  0.1] to have a smoother colour variation between neighbouring 
bins in the plotted intensity map. The plotted intensities with experimental data in Fig. 8a, 8c, 8e, 8g, 8i, 8k and 8l are 
produced by applying this smoothing matrix twice. For all other experimental data panels, 
the smoothing matrix is applied once. All calculation plots are unsmoothed.

plot_data.m code uses an internal function 'plot_color_fig' to reshape the data into 2D matrices and convert from bin centres to edges, 
and then uses pcolor with appropriate axes, colour limits and colour map.

plot_color_fig plots the colour data specified in the first argument, the second argument specifies whether the data
contains a column for errors, and the third argument
specifies whether smoothed intensities (default, flag=1), raw intensities (flag=0), or errors (flag=-1) should be plotted.

Energies are given in meV and (h,k,l) in rlu.
Where applicable, wavevectors are given in Cartesian coordinates (x,y) where x corresponds to (x,-0.5x,0) and y corresponds to (0,-y,0) in r.l.u.
Intensities and Errors are given in arbitrary units. 
Field is given in T.
