Fig. 40. Choose a Stripping File and Stripping Factor.
6.3.4. Smooth
The Smooth function transforms the data in the buffer according to a five-point, area-preserv-
ing, binomial smoothing algorithm. That is, the existing data are replaced, channel-by-channel,
with the smoothed data as follows:
where
S
i
= the smoothed data in channel i
O
i
= the original data in channel i
After S
i
is calculated, it is rounded off to the closest integer.
6.3.5. Strip...
When Strip... is selected, the dialog
shown in Fig. 40 opens, prompting
you for a filename and Stripping
Factor. The strip file should be a
valid
.MCS file containing the same
number of channels as the buffer.
Once you select a file and click
OK, MCS-32 strips the specified
disk spectrum from the spectrum in
the buffer and stores the result in
the buffer.
The Stripping Factor is a real
number that is multiplied, channel
by channel, by the disk spectrum
before being subtracted from the
buffer. This factor can be negative,
in which case the spectra are added.
If the Use Pass Count Ratio box in the file-recall dialog is marked, the strip factor is calculated
as the ratio of the pass count of the buffer spectrum to the pass count of the disk spectrum. The
pass count is not changed by any strip operation.
