Has anything changed recently that would affect SNSMO?

Using the clipping option, we are finding that it clips values that are
not outside the requested thresholds. Running the task in the 31DEC04
version of AIPS this does not occur. Appended below are my inputs and the
messages from the two versions of AIPS.
