% function simple_plots(plot2screen, plt_type, sineE, saveSNR,f,p);
% called from gnssIR_lomb.m
% inputs are boolean plot2screen and what plt_type (hardwired for now)
% variables to be plotted (sineE is sine of elevation angle and 
% saveSNR is the windowed SNR data with the direct signal removed)
% the remaining inputs are the periodogram
% data, which are in f and p (frequency and power).
% f units are meters (reflector height) and p is really amplitude 
% volts/volts
