Laboratory luminous efficiency results: iron and aluminum

This includes data presented in the paper "Experimentally derived luminous efficiencies for aluminum and iron at meteoric speeds", submitted to Geophysical Research Letters, as well as code to reproduce results plots. The contents include: al/fe_data: results from the aluminum and iron campaigns columns: particle velocity (m/s), particle mass (kg), luminous efficiency (unitless), luminous efficiency uncertainty (unitless) fe/al_fit.mat and fe/al_fit_gof.mat: output and goodness of fit statistics from fitting a rational function to the datasets paper_plots.m: basic plotting routines for the data and fits
