AST_READFITS

Read cards into a FitsChan from the source function

Description:

This routine reads cards from the source function that was specified when the FitsChan was created, and stores them in the FitsChan. This normally happens once-only, when the FitsChan is accessed for the first time. This routine provides a means of forcing a re-read of the external source, and may be useful if (say) new cards have been deposited into the external source. Any newcards read from the source are appended to the end of the current contents of the FitsChan.

Invocation

CALL AST_READFITS( THIS, STATUS )

Arguments

THIS = INTEGER (Given)
Pointer to the FitsChan.
STATUS = INTEGER (Given and Returned)
The global status.
