See S4testData excel sheet for drive point indices and coordinate systems

Info for "linearTest" folders:
	Naming Convention:
	Direction:
	-M2 = Z direction (mode 2 direction)
	-M6 = Y direction (mode 6 direction)
	Hammer
	-Sh = pencil hammer used
	Drive point (Dp):
	-See S4testData excel sheet for drive point indices
	-Drive point at each accel in order to mass normalize each mode
	-B200Z: DP1
	-N100Z: DP4, 100 side, nut side beam
	-N300Z: DP4, 300 side, nut side beam
	-B200Y: DP6, bolt side beam
	-N200Y: DP6, nut side beam
	AssembledLinear.mat stores data including Phi, the mass normalized mode shapes
	findPhi_v3.mat is used to calculate the modeshapes

Info for "NLTest" folders:
	Naming Convention:
	Direction:
	-M2 = Z direction (mode 2 direction)
	-M6 = Y direction (mode 6 direction)
	Hammer
	-Lh: Large hammer
	Drive point: see S4testData spreadsheet for indices
	Impact#: order that the impacts occured (some may be omitted)
	-###N: forcing amplitude in newtons.
	*_sourceData.mat files are modally filtered data (Q_NL is the modal coordinate)
	other files are timedomain throughput data.

	Variable names for *sourceData.mat
	Q_NL - modally filtered time response
	t - time vector
	Signal_0 - hammer output signal
	Signal_1 - accel. output signals
