CCD Photometry of NGC 2658, 2849, 3247
CCD photometry of the galactic open clusters NGC 2658, NGC 2849, and NGC 3247 is presented. For the first two clusters, BV(RI)_c data are given, and for NGC 3247 the data are... -
BVRI CCD photometry of 4 galaxy clusters
We have used the 2.3-meter Vainu Bappu Telescope to perform CCD imaging of X-ray-selected poor clusters of galaxies. Our sample consists of four X-ray luminous clusters in the... -
RcIcZ photometry of NGC 2547
We present a catalogue of RcIcZ photometry over an area of 0.855 square degrees, centred on the young open cluster NGC 2547. The survey is substantially complete to limits of... -
VIc photometry in Saurer A, B and C
We report deep (V~24.0) VI CCD photometry of three fields centred in the regions of the old open clusters Saurer A, B and C. In the case of Saurer A, which is considered one of... -
Faint galaxies KIc photometry
The excess number of blue galaxies at faint magnitudes is a subject of much controversy. Recent Hubble Space Telescope results have revealed a plethora of galaxies with peculiar... -
Phoenix Deep Survey: optical and NIR catalogs
The Phoenix Deep Survey is a multiwavelength galaxy survey based on deep 1.4GHz radio imaging. The primary goal of this survey is to investigate the properties of star formation... -
M31 Long Period Variables : Photometry
A significant fraction of the disk of M31 has been surveyed for long-period variable stars. We report the results, including near-infrared photometry of almost 2000 variables,... -
High proper-motion stars from MACHO astrometry
We present the preliminary results of our astrometric study of stellar motions along the lines of sight of the Magellanic Clouds and the Galactic bulge. Using 5 years of MACHO... -
Hubble Deep Field-South region
We present the galaxy-galaxy angular correlations as a function of photometric redshift in a deep, wide galaxy survey centered on the Hubble Deep Field-South (HDF-S). Images... -
UBVIc photometry of NGC 3077 center
We present UBVIc photometry of starlike objects in the central region of NGC 3077. The colour-colour and colour-magnitude diagrams of the objects are discussed. Many of the... -
Low-mass stars in the Cepheus OB2 region
We present the first identification of low-mass (spectral types K-M) stars in the young clusters Tr37 and NGC7160, members of the CepOB2 association. This is part of a program... -
LkH{alpha} 101 and the young cluster in NGC 1579
The central region of the dark cloud L1482 is illuminated by LkH{alpha} 101, a heavily reddened (A_V_~10mag) high-luminosity (>=8x10^3^L_Sun_) star having an unusual... -
HST UBVI photometry of NGC 3081 inner regions
We present Hubble Space Telescope Wide Field Planetary Camera 2 images of the inner regions of NGC 3081, an absolute magnitude M_B_=-20.0 early-type barred spiral having four... -
Cousins RI photometry in IC 348
The extremely young cluster IC 348 has been monitored photometrically over five observing seasons from 1998 December 10 to 2003 March 26 in Cousins I with a 0.6m telescope at... -
UBVRIz'HK' photometry of 2Ms CDFN X-ray sources
We present an optical and near-infrared catalog for the X-ray sources in the 2Ms Chandra observation of the Hubble Deep Field North region. We have high-quality multicolor... -
ESO 565-11 UBVI(c) photometry
We present multiband Wide Field Planetary Camera 2 images of the central regions of ESO 565-11, a peculiar southern barred galaxy recently shown to have the largest known... -
BVI photometry of nearby galaxies
Integrated CCD-photometry of the dwarf nearby galaxies in B, V and I (Cousins) bands is presented. The photometry was performed in increasing circular apertures. Cone search... -
BV(RI)c photometry of ON 231
We present the most continuous data base of optical multiband data ever published on the BL Lacertae object ON 231 (W Com). The data have been collected during an intensive and... -
ESIS BVR catalog, ELAIS-S1
The ESO-Spitzer extragalactic Imaging Survey (ESIS) is the optical follow up of the Spitzer Wide-Area InfraRed Extragalactic (SWIRE) survey in the ELAIS-S1 area. The... -
BV(RI)c photometry of S5 0716+714
We address the topic of the intra-night optical variability of the BL Lac object S5 0716+714. To this purpose a long-term observational campaign was carried out, from 1996 to...
