HST photometry: Can UV colors probe the galaxy ages? [PDF]
Astronomy and Astrophysics Supplement Series, 1997 We present grids of magnitudes and colours for the WFPC2 of the refurbished HST using pass- bands from the far UV to the near infrared, i.e. the lters F170W, F218W, F255W, F300W, F336W, F439W, F450W, F555W, F606W, F702W, F814W, and F850LP. In addition to this, we consider also the lters F150W+F130LP, F175W, F220W and F342W of the old HST in the FOC ...

3D-HST WFC3-selected Photometric Catalogs in the Five CANDELS/3D-HST Fields: Photometry, Photometric Redshifts and Stellar Masses [PDF]
The Astrophysical Journal Supplement Series, 2014 The 3D-HST and CANDELS programs have provided WFC3 and ACS spectroscopy and photometry over ~900 square arcminutes in five fields: AEGIS, COSMOS, GOODS-North, GOODS-South, and the UKIDSS UDS field. All these fields have a wealth of publicly available imaging datasets in addition to the HST data, which makes it possible to construct the spectral energy ...

HST/WFPC2 Photometry in the 30 Doradus Nebula Beyond R136 [PDF]
Symposium - International Astronomical Union, 1999 A photometric study of the 30 Doradus Nebula beyond the core is being carried out by means of HST/WFPC2 archival images, with special attention to the numerous multiple systems and compact clusterings found there.

HST/FGS Photometry of Planetary Transits of HD 209458 [PDF]
AIP Conference Proceedings, 2004 We present the data, and modeling and analysis results from the photometric monitoring of five planetary transits of HD 209458 using the Fine Guidance Sensors (FGS) onboard the Hubble Space Telescope (HST). We have now included the output from all four FGS photometers in our data reduction and analysis increasing our S/N over our previous results.

HST Survey of Clusters in Nearby Galaxies. I. Detection and Photometry [PDF]
The Astronomical Journal, 2001 We have developed photometric techniques that can be applied to images with highly-variable backgrounds, as well as to slightly-extended objects (object size comparable to or smaller than PSF size). We have shown that ordinary stellar PSF-fitting photometry can be applied to slightly-extended objects, provided that one applies a systematic correction ...

HST photometry of the binary globular cluster Sersic 13N-S in NGC 5128 [PDF]
Astronomy & Astrophysics, 2005 Using Hubble Space Telescope archival images we resolved individual stars in two young globular clusters centered in the giant HII region Sersic 13, on the dust band of NGC 5128. We resolved 5 sources in the southern cluster and 4 sources in the northern one.

Constraints on thick disc and halo parameters from HST photometry of field stars in the Galaxy [PDF]
Astronomy & Astrophysics, 2001 We analyse a sample of over 1000 stars from 32 fields imaged in the V and I bands with the Wide Field and Planetary Camera, on board of the Hubble Space Telescope. The fields are located at Galactic latitudes | b | >= 15deg and in various directions on the sky.

DEEPHST/ACS PHOTOMETRY OF THE M81 HALO [PDF]
The Astrophysical Journal, 2010 We present a deep color-magnitude diagram for individual stars in the halo of the nearby spiral galaxy M81, at a projected distance of 19 kpc, based on data taken with the Advanced Camera for Surveys on the Hubble Space Telescope (HST). The color magnitude diagram reveals a red giant branch that is narrow and fairly blue, and a horizontal branch that ...
