% SUMMARY: ATM_PLOT_WVFMS plots ATM waveform data stored in a stuctured array created by ATM_WVFM_READER
%
% The number of input arguments must be between 2 and 5 with the following options:
% SYNTAX: plt_wvfms(wvfm_struct,shot_list);
% SYNTAX: plt_wvfms(wvfm_struct,shot_list,t_min);
% SYNTAX: plt_wvfms(wvfm_struct,shot_list,t_min,t_max);
% SYNTAX: plt_wvfms(wvfm_struct,shot_list,t_min,t_max,back_ground_color);
%
% wvfm_struct: First input argument must be a stuctured array created by ATM_WVFM_READER
%
% shot_list: Second input argument must be a row or column vector of shot indices to be plotted.
%
% t_min, t_max: Laser trigger time in nano seconds. PLT_WVFMS plots only range gates with t >= t_min and t <= t_max
% t_max can be let unset or set to Inf to include all range gates after t_min
% The two parameters can be used to select window reflections, transmit pulses or returns from targets
% The time of the window reflection and transmit pulse changes with installations and needs to be
% adjusted accordinly.
% A good starting point to only plot windwow reflections is
% t_min = 0, t_max = 80
% Plot only transmit pulses:
% t_min = 80, t_max = 200
% Plot all target returns without window reflections or transmit pulses
% t_min = 200, tmax = Inf (or left blank)
%
% The time windows for window reflections, transmit pulse and return pulsea to use for the particular data file
% are campaign and instrument dependent and are listed in the HDF5 fields /waveforms/twv/ancillary_data/rx_start,
% ./tx_start and ./tx_end in number of digitizer samples.
%
% back_ground_color: can be 'w' (white) or 'b' (black). If not set PLT_WVFMS create a figure with black background by default.
