AST_DELFITS
-
Delete the current FITS card in a FitsChan
Description:
This routine deletes the current FITS card from a FitsChan. The
current card may be selected using the Card attribute (if its index
is known) or by using AST_FINDFITS (if only the FITS keyword is
known).
After deletion, the following card becomes the current card.
Invocation:
CALL AST_DELFITS( THIS, STATUS )
Arguments:
THIS = INTEGER (Given)
Pointer to the FitsChan.
STATUS = INTEGER (Given and Returned)
The global status.
Notes:
This function returns without action if the FitsChan is
initially positioned at the "end-of-file" (i.e. if the Card
attribute exceeds the number of cards in the FitsChan).
If there are no subsequent cards in the FitsChan, then the
Card attribute is left pointing at the "end-of-file" after
deletion (i.e. is set to one more than the number of cards in
the FitsChan).
