SPOTTRAN


 The SPOTTRAN card is used in conjunction with SPOTBEAM, SPOTDIR and
 SPOTPOS to define transformation of multiple beam spots.

 Warning : These four cards are activated only by indicating 
SDUM
= BEAMSPOT in the SPECSOUR card. Barring this, the spot cards will be discarded. See also SPOTBEAM, SPOTDIR, SPOTPOS
WHAT(1)
= index or name of a transformation to be copied into the one defined by
WHAT(2)
A -99999 value means unit transformation, whichever other negative value resets to default Zero is ignored
Default
: 0 - no transformation
WHAT(2)
= index or name of a transformation to be overwritten by that defined by
WHAT(1)
A negative number resets to default Zero is ignored
Default
: 0 - no transformation
WHAT(3)
= not used
WHAT(4)
= from spot number
WHAT(4)
...
Default
: 0
WHAT(5)
= ... to spot number
WHAT(5)
...
Default
:
WHAT(4)
WHAT(6)
= ... in step of
WHAT(6)
Default
: 1
SDUM
: DIRECT : the WHAT(1/2) transformation is applied to the beam spot position and axes as well INVERSE: the WHAT(1/2) inverse transformation is applied to the beam spot position and axes no
SDUM
: no transformation is applied to the beam spot position and axes
Default
: no
SDUM
When a beam spot in the range indicated by WHAT(4/5/6) is selected the transformation indicated in
WHAT(2)
is overwritten by the one indicated in
WHAT(1)
. This allows to use a generic transformation (
WHAT(2)
) for all parameters/cards which require different ones for different beam spots. Please note that the transformation
WHAT(2)
is not restored after being overwritten
