realnum t_geometry::covaper

the aperture covering factor; must be between 0 and 1: iEmissPower == 2 : in this case the variable is set equal to covgeo iEmissPower == 1 : the fraction of a large circle in the plane that is being observed that actually passes through nebular material. iEmissPower == 0 : is gas present only at the front or the back (D_0 = 1/2) or on both sides (D_0 = 1) of the central source. this is the variable D_alpha in the Hazy discussion of the APERTURE command

Referenced by InitDefaultsPreparse(), ParseAperture(), ParseCommands(), PrtComment(), PrtFinal(), and ZoneStart().

realnum t_geometry::covgeo

default open geometry, covgeo is unity, covrt is zero. closed geometry, covgeo is unity, and covrt is unity linearly affects line luminosities but not intensities (since they are per unit area of cloud. When sphere command is entered with no optional covering factor this is set to 1 and covrt is set to covgeo. The default is an open geometry, and covgeo is unity for this as well

Referenced by conorm(), ConserveEnergy(), flxCell(), lines_continuum(), lines_hydro(), ParseCommands(), ParseCovering(), ParseSphere(), PrtFinal(), sum_radiation(), zero(), and ZoneStart().

realnum t_geometry::covrt

radiative transfer covering factor accounts for diffuse radiation escaping from system in open geometry. weakly affects intensities and luminosities. For open geometry this is zero (half of diffuse fields escape from cloud and do not strike gas, for a closed geometry this is unity also set to covgeo (def unity) if covering factor command is entered

realnum t_geometry::DirectionalCosin

1/cos incident continuum entering AngleIllumRadian from normal - this is 1./cos(normal), so > 1.

long int t_geometry::iEmissPower

this is the power of r that is used in the line flux integral 2 : default case - integrate the whole (spherical) nebula 1 : simulate a long slit over the central source 0 : simulate a pencil beam centered on the central source this is the variable alpha in the Hazy discussion of the APERTURE command
