SPOTPOS


 The SPOTPOS card is used in conjunction with SPOTBEAM and SPOTDIR
 to define multiple beam spots. A new primary is created randomly
 in any of the listed beam spots according to their respective weight
 or in sequential order (see SPECSOUR).

 Warning : These four cards are activated by indicating 
SDUM
= BEAMSPOT in the SPECSOUR card. Barring this, the spot cards will be discarded. See also SPOTBEAM, SPOTDIR, SPOTTRAN
WHAT(1)
= x-position of the beam spot
WHAT(2)
= y-position of the beam spot
WHAT(3)
= z-position of the beam spot
WHAT(4)
> 0.0 : rectangular beam width in x-direction or maximum beam radius depending on
WHAT(6)
(cm) < 0.0 : Gaussian beam profile in the x-direction.
WHAT(4)
is the FWHM in cm = 0.0 : pencil beam along x
Default
: 0.0
WHAT(5)
> 0.0 : rectangular beam width in y-direction or minimum beam radius depending on
WHAT(6)
(cm) < 0.0 : Gaussian beam profile in the y-direction.
WHAT(5)
is the FWHM in cm = 0.0 : resets to default is no annular beam spot requested (see
WHAT(6)
), ignored otherwise
Default
: same as x-width if no annular beam spot requested (see
WHAT(6)
)
WHAT(6)
> 0.0 : flag for a rectangular beam spot < 0.0 : flag for an annular beam spot = 0.0 : ignored
Default
: 0.0
SDUM
: Beam spot number (free format)
Default
: n, the number of the last defined spot
Notes:
1) If no SPOTPOS card is issued for an otherwise (via SPOTBEAM) defined beam spot, the spot position and position spread are taken from the BEAM and BEAMPOS cards
