a with roving Ref are detected (number of refs &gt;
 number of responses), H is automatically transposed and RespDof and
 RefDof are reversed. This means that the code for processing of H

 NOTE! For some applications you may need to read both auto and
 cross-spectra or correlation functions; then specify a vector for
 FuncType. For example for (correlation based) OMA, specify function
 t
