SUCONV - convolution with user-supplied filter

suconv <stdin >stdout filter= [optional parameters]

Required parameters: ONE of
sufile= file containing SU trace to use as filter
filter= user-supplied convolution filter (ascii)

Optional parameters:
none

Trace header fields accessed: ns
Trace header fields modified: ns

Notes: It is quietly assumed that the time sampling interval on the
single trace and the output traces is the same as that on the traces
in the input file. The sufile may actually have more than one trace,
but only the first trace is used.

Examples:
suplane | suwind min=12 max=12 >TRACE
suconv<DATA sufile=TRACE | ...
Here, the su data file, "DATA", is convolved trace by trace with the
the single su trace, "TRACE".

suconv<DATA filter=1,2,1 | ...
Here, the su data file, "DATA", is convolved trace by trace with the
the filter shown.

CAVEATS: no space-variable or time-variable capacity.
The more than one trace allowed in sufile is the
beginning of a hook to handle the spatially variant case.
