For each function chosen in the interspectrum, POST_DYNA_ALEA stores in a table accessible by IMPR_TABLE [U4.91.03]

• spectral moments

• statistical parameters (to be used if it is an autospectrum):

• standard deviation,

• irregularity factor,

• average number of extrema per second,

• number of zeros per second,

• center frequency

• the peak factor according to Vanmarcke’s formula

• the average maximum according to the Vanmarcke formula
