DESPIKE

        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
    despiked.

    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.
