  • NGC 2366, NGC 2403 & NGC 4236 HK' photometry

    Near Infrared H and K' surface photometry of the three nearby galaxies NGC 2366, NGC 2403 and NGC 4236, used as local calibrators of the Tully-Fisher relation, was obtained...
  • OGLE RR Lyr stars in omega Cen

    Table 1 lists light curve parameters and rectangular coordinates for variables OGLEGC 71-211. Table 2 contains equatorial coordinates of variables OGLEGC 71-211. Tables (table3...
  • DD Mon BV light curves

    New BV light curves of the short-period eclipsing binary system DD Mon have been obtained. Light-curve variability is seen in both B and V bands as compared with the light...
  • Nearby clusters of galaxies properties. III.

    This paper is the third of a series (Trevese et al. 1992, Paper I, Cat. , Flin et al. 1995, Cat. , Paper II, presenting F band photometry, from digitized 48-inch Palomar plates,...
  • The globular cluster NGC 1904

    Table 2 contains CCD UBV photometry of 2451 stars in the globular cluster NGC 1904. In the printed version, only the first 30 lines of the table were presented for guidance.
  • uvby photometry of 4 CP stars

    Differential Stroemgren uvby photometric observations from the Four College Automated Photoelectric Telescope are presented for four magnetic chemically peculiar stars....
  • BV photometry in the LMC bar

    We present B, V magnitudes and relative positions for all brighter than V=18.3 in a field of 0.02 square degrees near the north west end of the Large Magellanic Cloud bar. These...
  • Clusters and field stars in LMC. I.

    We present CCD photometry in the Johnson BV system to about V=23^m^ for the stars in six clusters and the surrounding fields in two regions of different nature in the Large...
  • Clusters of galaxies properties. II.

    We present F band photometry, from digitized 48-inch Palomar plates, of 1167 galaxies brighter than m_3_ +3 in 10 Abell clusters. For each galaxy, absolute coordinates,...
  • Mixed pairs of galaxies. I.

    We present data from a kinematic and photometric study of six mixed pairs. High resolution rotation and velocity dispersion curves, for both gas and stellar components, are...
  • CCD photometry of Pal 1

    A CCD photometry of the halo cluster Palomar 1 is presented in the Thuan-Gunn photometric system. The principal sequences of the color-magnitude diagrams are delineated in...
  • Deep photometry of NGC 5694 and Terzan 8

    We present deep CCD photometries for the little known metal-poor clusters NGC 5694 and Terzan 8 down to V~24. NGC 5694 has a blue horizontal branch, a very high radial velocity,...
  • V,I CCD photometry of NGC 6528

    We present CCD photometry in V and I for the metal-rich globular cluster NGC 6528. A comparison with previous photometry reveals discrepancies of the order 0.1 to 0.2mag in V,...
  • Gamma-ray loud blazars optical monitoring. II.

    New data from the optical monitoring of gamma-ray loud blazars at the Torino Astronomical Observatory are presented.
  • Variations of Ap stars in the Geneva system

    The photometric behaviour of 21 Ap stars has been analyzed from observations obtained in the Geneva system. Variability has been detected for 9 Ap stars, as well as for a star...
  • UBV(RI)c photometry of active stars. VII.

    In the framework of an extensive program focusing on the global properties and evolution of active stars, high-precision UBV(RI)c photometry of 19 selected stars, collected at...
  • VI photometry of Westerlund 1 and 2

    We have carried out CCD observations of stars in the region of the open cluster Westerlund 1 through the V and I passbands. The direct images were obtained with the 24-inch...
  • uvby-beta photometry in SA 203

    Results are presented of Stromgren uvby(beta) photometry for 213 stars earlier than G0 and brigher than mpg of about 10.7mag in Selected Area 203. The observed area lies close...
  • IR Stellar Population in Baade's window

    The 2.2um (K) scan (table1) was made on the Mt. Stromlo 1.9m telescope with the MSO IR-photometer, during several observation sessions in 1981, at sideral rate with a 12arcsec...
