C120111104_real_30_ns00000.txt   -->   exponential electrical pulse readout into 50 Ohm load
                                       the rise time constant is chosen to match the one calculated
                                       by Yimin and used by Syed for optimum excitation of the atom.

C120111104_real_30_ns00001.txt   -->   exponential pulse mixed with rf at 1.5 GHz. This is the signal that
				       is eventually fed into EOM

C220111104_real_30_ns00000.txt   -->   driving NIM pulse measured with high impedance passive probe

C220111104_real_30_ns00001.txt   -->   collector voltage of T1 transistor measured with high impedance passive probe

C220111104_real_30_ns00002.txt   -->   base voltage of T1 transistor measured with high impedance passive probe

OD_in_0.00_OD_out_1.8_2.9_after_histo_wo_atom_to_fit --> raw data file with processed timestamp events. The relevant columns
                                                         are 2:11:13 that is time:normalized probability of detecting
                                                         photon in transmission arm:errorbars. The OD's in filename tag
                                                         the optical density of filters used to change photon number on input 
							 (OD_in) and before the APD, so it is not saturated (OD_out)


Added on 31.1.2012:
Common traces that capture input pulse, basis voltage and output pulse for one
setting (Vcontol=1.4V)
