4. Verification phase

Various checks are carried out to ensure that the data are coherent (nb_poin sufficiently large in relation to the maximum frequency and the duration to be generated, sufficiently large duration in relation to the discretization of the interspectrum, etc…). Alarms are issued if necessary.

If the NB_POIN keyword is present, then we check that the given value is a power of 2. If not, an alarm is issued and the value is changed.

If INTERPOL =” NON “, it is verified that the various terms of the interspectral matrix have the same discretization with a constant frequency step.
