crg_separator_volts_to_angle (ul_crg)

	status.i4.v = crg_separator_volts_to_angle(file_number.i4.v,
						   energy.r4.v, angles.r4a.r,
						   volts.r4a.r, plane.i4.v)

	Convert an array of separator volts to an array of angles.

       file_number	which CRG file number to take the calcuation
			constants from
	energy		the energy for these angles
	angles		An array of separator angles in urad. These are
			put in the order displayed in the CRG application.
			This should be preallocated by the user.
	volts		An array of the voltage values.  These are assumed
			to be in the order of the display in the CRG
			application.  This array should be preallocated by
			the user.
