Description:
Table 2 presents standard broad band U, B, V, R photoelectric
photometry of AX Persei. Each value represents the average of the
observations during a night. The uncertainty of these night-means is
of a few x 0.001mag in the B, V and R bands, and up to 0.02mag in
the U band. Table 3 presents observed spectrophotometric parameters of
the spectrum: the line fluxes, fluxes in the local continuum and the
radial velocities.
