Field Documentation

◆ covaper

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

Definition at line 44 of file geometry.h.

◆ covgeo

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

Definition at line 35 of file geometry.h.

◆ covrt

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

Definition at line 51 of file geometry.h.

◆ DirectionalCosin

realnum t_geometry::DirectionalCosin

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

Definition at line 15 of file geometry.h.

◆ FillFac

realnum t_geometry::FillFac

FillFac is filling factor, default 1, others are parameters to make function of radius

Definition at line 19 of file geometry.h.

◆ filpow

realnum t_geometry::filpow

Definition at line 20 of file geometry.h.

◆ fiscal

realnum t_geometry::fiscal

Definition at line 21 of file geometry.h.

◆ iEmissPower

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

Definition at line 61 of file geometry.h.

◆ lgEndDflt

bool t_geometry::lgEndDflt

lgEndDflt true if still at default

Definition at line 96 of file geometry.h.

◆ lgGeoPP

bool t_geometry::lgGeoPP

true if geometry is plane parallel, set in comment

Definition at line 11 of file geometry.h.

◆ lgSizeSet

bool t_geometry::lgSizeSet

has the aperture size been set by the user?

Definition at line 70 of file geometry.h.

◆ lgSphere

bool t_geometry::lgSphere

flag saying whether spherical geometry

Definition at line 24 of file geometry.h.

◆ lgStatic

bool t_geometry::lgStatic

flag saying that spherical geometry is static, set with sphere static

Definition at line 54 of file geometry.h.

◆ lgStaticNoIt

bool t_geometry::lgStaticNoIt

flag saying that it is ok to not iterate when sphere static is set, set with (OK) option on sphere static, used for testing hydrogen atom

Definition at line 74 of file geometry.h.

◆ lgZoneSet

bool t_geometry::lgZoneSet

lgZonSet set if stopping zone specified

Definition at line 87 of file geometry.h.

◆ lgZoneTrp

bool t_geometry::lgZoneTrp

lgZoneTrp set if stopped due to zone number

Definition at line 90 of file geometry.h.

◆ nend

long int* t_geometry::nend

nend[iteration] is limiting number of zones for that iteration <[ITR DIM]

Definition at line 80 of file geometry.h.

◆ nend_max

long int t_geometry::nend_max

Definition at line 84 of file geometry.h.

◆ nEndDflt

long int t_geometry::nEndDflt

default limit to number of zones

Definition at line 93 of file geometry.h.

◆ nprint

long int t_geometry::nprint

nprint is how many zones to print

Definition at line 77 of file geometry.h.

◆ size

realnum t_geometry::size

size of the aperture: iEmissPower == 2 : in this case the variable is not used iEmissPower == 1 : slit width in arcsec iEmissPower == 0 : surface area of the pencil beam in arcsec^2
