| Abstract: | The Pulkovo Spectrophotometric Data Base is used to determine the expansion velocities and radii of the continuum emission
layers of the stars RR SCO and OMICR CET. Dependences of the radii and velocities on the phase of the variability cycle are
found which agree with the known values obtained from the layers which emit line radiation.
