MIRA\DESPIKE [ifb] [/PIXEL [ipix]] [/ITERATE niter]
[/WINDOW vMin vMax] [/THRESHOLD value]
DESPIKE removes spikes from spectra, OTF data, and continuum drifts, re-
spectively. If the frontend-backend identification number ifb is not
specified, the first frontend-backend combination of the current scan is
DESPIKE /PIXEL [ipix]
Allows to specify the pixel number ipix for array observations. Default
is pixel 1 (for HERA1 and HERA2: pixel 5, the central one).
DESPIKE /ITERATE niter
Allows to remove up to niter spikes (default is niter = 10).
DESPIKE /WINDOW vMin vMax
Spectral channels with velocities between vMin and vMax are not consid-
ered in the search for spikes. Used to avoid confusion between e.g. nar-
row spectral lines and spikes.
DESPIKE /THRESHOLD value
By default, the threshold for searching for spikes is 5 sigma (rms),
i.e. records where the difference between the data value and the median
of the spectrum or the time series is higher than 5 sigma are despiked
(i.e. attributed the blanking value). With option /THRESHOLD, the
threshold can be set to another value.
