Description:
This routine searches the
supplied CmpFrame for an axis that is a SpecFrame. It returns the axis index of the SpecFrame within
the CmpFrame, and also returns a pointer to the SpecFrame itself.
No error is reported if the CmpFrame does not contain a SpecFrame. If the CmpFrame
contains more than one SpecFrame, the first (i.e. the lowest index) is returned.
Invocation
CALL ATL_FSPEC( FRM, SPAX, SPFRM, STATUS )
Arguments
FRM= INTEGER (Given)
The CmpFrame pointer.
SPAX = INTEGER (Returned)
The index of the spectral axis
within the CmpFrame. Returned equal to zero if no spectral axis is found.
SPFRM =
INTEGER (Returned)
A pointer to the SpecFrame. Returned equal to AST__NULL if no
spectral axis is found.
STATUS = INTEGER (Given and Returned)
The global status.
