calcPerform

[Dirk Zimoch <dirk.zimoch@psi.ch>]

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
