Long-term photometry of variables at ESO. I - The first data catalogue (1982-1986)
This paper presents the catalog of photometric data in the Stromgrensystem obtained during the first four years (October 1982 - September1986) of the Long-Term Photometry of Variables (LTPV) program at ESO.The data are available in computer-readable form.

Photometric variations of 46 Eridani and 210 G. Eridani
The photometric behavior in the uvby system of the Ap star 46 Eri isanalyzed on the basis of new data. The revised period is P = 3.798777 +or - 0.000015 d. Knowledge of the accurate light-curve of 46 Eri makesit possible to refine data on the multiperiodic B5III variable star 210G. Eri, which was used as a comparison for 46 Eri. Four periods, all ofthe order of four days, are found with P(1) = 3.9215 d standing outclearly. This value is very large compared to those of other mid-Bvariables.
