decimate |
procedure decimate[, nchan], [startat=integer], [buffer=buffer], [ok=variable] |
This procedure thins the spectrum at the primary data container (the PDC, buffer 0) by selecting out and keeping the data at every nth channel. This can also operate on other buffers.
The frequency interval and reference channel are adjusted appropriately so that the x-axis labels for the decimated data are still appropriate.
This can not be used on continuum data containers.

Parameters | |
nchan |
Thin the spectrum by keeping the value at every nchan channels starting from the startat channel This defaults to 2. |
