[These options are same as the options in MO 3 except for the capabilities of the SP/SPA/SPV options. Thus, for the other options see MO 3]
Option "SP" - SPhere. Spheres of given outer and inner radius with a given density are created, with centers located at specified points. The default inner radius is zero and the default density value is 2.0. The default coordinates of the center are (NSAM/2+1, NROW/2+1, NSLICE/2+1). After modelling a sphere of a given radius the program asks for the radii and location of the next sphere. If the outer radius + the any of the center coordinates exceeds the boundary of the 3-D file, the program warns that part of the sphere will be truncated. To exit enter 0,0 or space as radius. This information is entered via a document file.
Option "SPV" - SPheres Variable Added to old file. Same as SP except that mass values are read from the document file instead of being set the same for all spheres. The mass values are in the column following the radii (if the radii are in the document file). The only difference for SPVA is that it adds the spheres to an existing 3-D file.
.NUMBER OF SPHERES, STARTING COL. FOR X,Y,Z: 50,1
[Enter number of spheres and column of x-coordinate
in document file]
.X,Y,Z -OFFSET: 20.,-10.,51.
[Enter offset for X,Y,Z]
.OUTER AND INNER RADIUS OF SPHERE (FL.PT.): 4.5,1.7
[Enter radius of sphere as a floating point number.
If a negative value is entered for one or both of the
radii, they are taken from the document file. If
the inner radius is taken from the document file, the
outer radius also m u s t be in this file, the outer
radius can be taken from the document file while the inner
one can be fixed for all spheres and enetered explicitely.]
