Example-Based Multispectral Photometric Stereo for Multi-Colored Surfaces

Journal of Imaging, 2022
A photometric stereo needs three images taken under three different light directions lit one by one, while a color photometric stereo needs only one image taken under three different lights lit at the same time with different light directions and ...

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.

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.

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.

Atmospheric Extinction Corrections for WET Observations

Open Astronomy, 2003
Account of the extinction in the Earth’s atmosphere is an important part of the WET light curve reduction procedures. Usually, WET observations are not corrected for the second order extinction effects: the dependence of the extinction coefficient on ...
