Hi folks,
some time ago, Timo Korhonen has patched the calcPerform function to
return -1 (=error) if the result of the calculation is nan. This has
been done to raise an INVALID_ALARM and not to process the OUT link if
IVOA="Don't drive outputs". (That required a patch of the calcout
record, too. But that's an other story.)
My question is: should calcPerform return -1 as well if the result is
inf (or -inf) ?
Awaiting your comments,
Dirk
