[daip] CLCAL and flagged SN table solutions

Hi Eric et al., I have a quick question about CLCAL for you,
I would like CLCAL to smooth and apply a SN table for which some of the entries
have been flagged previously with
SNEDT. (These entries thus have weight = -1). When I run CLCAL with the inputs
below, it completely
ignores the flags, and uses all of the SN table entries. Is there any parameter
that controls this behavior?
Perhaps I'm missing something. I've tried doblank = -1, 0, 1, and all give the
same result.
Thanks,
Matt
