A homogeneous catalog of new UBV and H-beta photometry of B- and A-type stars in and around the Scorpius-Centaurus OB association
B- and A-type stars in and near the Sco-Cen OB association areinvestigated with UBV and H-beta photometry to acquire data relevant tothe luminosity function of Sco-Cen. The measurements generally consistof two 10-s integrations of U, B, V, (W, N) filters, and theobservations are corrected iteratively for atmospheric extinction andinstrumental response. The data presented give the mean V magnitude,mean B-V, mean U-B, and the estimated uncertainties for these values.The catalog provides a homogeneous catalog of data for a large fieldwith stellar objects delineating membership to the association Sco-Cenand that affect the luminosity function of the aggregate.

Spectrophotometry in the upper Scorpius region
The low dispersion spectrophotometric measures of 29 stars in the upperScorpius region, made from 1964 to 1969 with an old-type spectrumscanner, employing a 91 cm telescope with a 60 A slit, are examined.Equivalent widths of H-beta, H-gamma, and H-delta are measured alongwith the size of the Balmer discontinuity, the gradients in theultraviolet and the blue-green-yellow parts of the spectrum. The resultsof the intensity distributions, the spectral intensity distributions,and some measured quantities are presented in tabulated form.
