The ALHAMBRA photometric system [PDF]
The Astronomical Journal, 2010 This paper presents the characterization of the optical range of the ALHAMBRA photometric system, a 20 contiguous, equal-width, medium-band CCD system with wavelength coverage from 3500A to 9700A.

Thermodynamic and structural studies of complexes of manganese(II), cobalt(II), nickel(II) and copper(II) with aminofuropyridine carboxamide [PDF]
Journal of the Serbian Chemical Society, 2003 Complexes of Mn(II), Co(II), Ni(II) and Cu(II) with 2-aminofuro[3,2-b]pyridine-3-carboxamide have been prepared. The stability constants of the formed complexes were determined at 20, 30, 40 and 50ºC at a fixed ionic strength, I = 0.1 mol dm-3 (KCl). The

The New Ephemeris and Light Curve Analysis of V870 Ara by the Ground-Based and TESS Data
Open Astronomy, 2021 New CCD photometric observations and their investigation of the W UMa-type binary, V870 Ara, are presented. Light curves of the system were taken through BVIfilters from the Congarinni Observatory in Australia.

An Attempt to Construct an Activity Cycle Catalog with Kepler Long-Cadence Light Curves
Universe, 2022 Many stars show activity cycles like the Sun. Kepler has gathered ∼200,000 light curves. Most of the Kepler stars only have long-cadence light curves, which limits their applicable methods.

Multiview Photometric Stereo [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2008 This paper addresses the problem of obtaining complete, detailed reconstructions of textureless shiny objects. We present an algorithm which uses silhouettes of the object, as well as images obtained under changing illumination conditions. In contrast with previous photometric stereo techniques, ours is not limited to a single viewpoint but produces ...

Photometric redshifts from reconstructed QSO templates [PDF]
, 2001 From SDSS commissioning photometric and spectroscopic data, we investigate the utility of photometric redshift techniques to the task of estimating QSO redshifts. We consider empirical methods (e.g.

The GALANTE photometric system [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 This paper describes the characterization of the GALANTE photometric system, a seven intermediate- and narrow-band filter system with a wavelength coverage from 3000 $ $ to 9000 $ $ . We describe the photometric system presenting the full sensitivity curve as a product of the filter sensitivity, CCD, telescope mirror, and atmospheric transmission ...

Photometric Redshifts of Galaxies in COSMOS [PDF]
, 2006 We measure photometric redshifts and spectral types for galaxies in the COSMOS survey. We use template fitting technique combined with luminosity function priors and with the option to simultaneously estimate dust extinction (i.e. E(B-V)) for each galaxy.

Photometric Redshifts of Quasars [PDF]
, 2001 We demonstrate that the design of the Sloan Digital Sky Survey (SDSS) filter system and the quality of the SDSS imaging data are sufficient for determining accurate and precise photometric redshifts (``photo-z''s) of quasars.
