Stellar uvbybeta photometry in three EUV shadow directions
We present the uvbybeta data used to locate the dust and derivedistances for nearby diffuse interstellar clouds in the EUV shadowslb27-31, lb165-32 and lb329+46 discovered by the Extreme UltravioletExplorer. The photometrically derived parallaxes of our program starsare compared to the parallaxes listed in the Hipparcos Catalog. Withinthe photometric distance limit of 150 pc, the photometric parallaxes of21 ``normal" stars are consistent with the Hipparcos measurements withinan uncertainty of 15%. Much as expected for the Str{ömgren system.Since all program stars are brighter than V~11.5 most of them areincluded in the Tycho photometry. For our sample of ~ 200 stars we findVby and V_T to be consistent. Few stars are common topublished uvbybeta catalogs, ~ 10, V and the indices compare well apartfrom beta where a zero point difference of 11 mmag is noticed.Tables \ref{tab1}-\ref{tab3} are also available in electronic form atthe CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or viahttp://cdsweb.u-strasbg.fr/Abstract.htmlBased on observations at the European Southern Observatory, La Silla,Chile.
