I) ENVELOPE DESCRIPTION

	A) MODEL COMPONENTS
		Wind = 0			!Is a stellar wind present?
		Disk = 1			!Is the disk present?
		Dust = 0			!Is there a dusty region exterior to the gas?

	B) DIMENSIONS
		R_env  = 18.6		!envelope outer radius (must be larger than the 

	C) DENSITY

		b) DISK DENSITY
			i) SURFACE DENSITY = 1
				1) POWER-LAW		!(SURFACE DENSITY = 1): radial power law
					n = 2.0			!radial exponent 

				2) STEADY-STATE DECRETION DISK	!(SURFACE DENSITY = 2): VD
					alpha = 1.  !alpha disk parameter (Shakura & Sunyaev)
					R0 = 0.
					ITERATE SURFACE DENSITY = 0 !(0 = no) OR (1 = yes)

				4) 1-D FILE			!(SURFACE DENSITY = 4): 1-D SD from a file
					File = 'deltasco/Atsuo/1D/data/dSco_a035_01'
					Time = 2.3 yrs  !which time (epoch) to read from the file

			ii) VERTICAL DENSITY = 0
				0) GAUSSIAN		 !(VERTICAL DENSITY = 0)
					betad = 1.5 !disk flaring parameter.

				1) HSEQ VD			  !(VERTICAL DENSITY = 1)
					betad = 1.5 !disk flaring parameter (used to define the disk

			iii) VERTICAL SCALE HEIGHT = 1
				 1) ACTUAL TEMPERATURE
					Teff_SH = 18000. K	!Effective temperature for setting the  
										!scale height.  
				 2) FRACTION OF TEFF OF PRIMARY STAR
					Fraction = 72.%
				
			iv) DISK SURFACE
				RATIO = 1.E7

	D) DENSITY SCALE
		b) DISK DENSITY MODE = 2
			2) BASE DENSITY			 	!(DISK DENSITY MODE = 2)
				!requires SURFACE DENSITY = 1
				n_0 = 2.35E13 cm^-3	 	!number density at r=R
			3) MASS LOSS RATE			!(DISK DENSITY MODE = 3)
				!requires SURFACE DENSITY = 2
				Mdot = 1.E-9 Msun/yr  !mass loss rate

	E) VELOCITY FIELD						! (velocities must be in km/s)
		b) DISK VELOCITY = 3
			3) KEPLERIAN ROTATION			!(DISK VELOCITY = 3); Pure rotation
				V_orb = -1 km/s				!orbital speed at stellar radius

		d) TURBULENT VELOCITY 
			V_turb = 0. km/s !turbulent velocity; sets line profile width
