RESAMPLE SHAPE

Four keywords are used to describe the frequency response of the synthe-
sized channels:
- TBOX means a rectangular function in the delay domain, as for un-
smoothed correlator channels (sin(pi.x)/(pi.x) in the frequency
domain)
- TPAR means a parabolic function in the delay domain, as for smoothed
correlator channels (smoothing function used at Plateau de Bure)
- FBOX means a rectangular function in the frequency domain (as for fil-
terbank channels)
- FTRIANGLE means a triangular function in the frequency domain (as for
filterbank channels, Hanning smoothed)
The shape of the input channels is derived from the backend number read
in the telescope name for IRAM-30m spectra: TBOX for autocorrelator,
FBOX for other (filter) backends. Otherwise, rectangular filter channels
are assumed.
