Description of the input parameters for BM:
               ===========================================

MACHINE NAME:   Information title

B FROM:For selecting B field from either Magnetic radius of the bending 
	magnet or magnetic field.
	(The three precedent parameters are related by:
	Radius [m] = (10/3) * Energy[GeV] / B[Tesla])

MACHINE RADIUS: The radius of the Bending Magnet in meters.

MAGNETIC FIELD: The magnetic field of the bending magnet in Tesla.

BEAM ENERGY:    The electron beam energy in GeV.

BEAM CURRENT:   The electron beam current in Ampers.

HORIZ DIV:      The horizontal divergence in mrad.

PSI (VERTICAL DIV) FOR ENERGY SPECTRA: For the calculation of the FLux and 
		Power density spectra, different options of Psi can be selected:
	Full (integrated in Psi): Spectra are calculated integrated from all 
		space over Psi
	At Psi=0: Spectra (pre mrad in Psi) at the center of the beam Psi=0 
	In [Psi_Min,Psi_max]: Spectra integrated over a given interval in Psi. 
		The values of the interval (Psi_Min and Psi_max) must be 
		entered and also the mumber of points for integration in Psi. 

MIN PHOTON ENERGY:  Minimum photon energy for the calculated spectrum, in eV.

MAX PHOTON ENERGY:  Maximum photon energy for the calculated spectrum, in eV.

NUMBER OF ENERGY POINTS: Number of energy points for the energy spectra

SEPARATION BETWEEN ENERGY POINTS: Two options are available for creating the 
		energy array: 
	Lin: Energy points are a linear array (constant step)
	Log: Energy points are a logarithmic array (step changes as log)

MAX Psi[mrad] FOR ANGULAR PLOTS: Define the maximum value of Psi in mrad to 
		be used when selecting the angular distribution plots, i.e.:
	Plot angular distribution (all wavelengths) 
	Plot angular distribution (one wavelength) 

Psi min [mrad]: minimum value of Psi [mrad] for integration. Used in
	Plot energy spectra in [Psi_Min,Psi_Max] angular range
	Plot (angular,energy) distribution
    Use also this entry to place the Psi value to be used when calculating 
	Plot energy spectra at Psi=Psi_Min

NUMBER OF PSI POINTS: Number of points for Psi integration or for the 
	(angular,energy) mesh distribution. Please note that in the case that 
	an integration over an angular interval [Psi_Min,Psi_Max] is chosen, 
	the accuracy of the result may depends on this number of points in 
	the integration grid.
