TL;DR: In this article, a measurement of the microlensing optical depth toward the Galactic bulge based on the analysis of 15 contiguous1 square degrees fields centered on (l=2.5 deg, b=-4.0 deg) and containing 1.42 million clump-giant stars (belonging to the extended clump area) monitored during almost three bulge seasons by EROS (Experience de Recherche d'Objets Sombres).

TL;DR: In this article, the authors present an analysis of the light curves of 9.1 million stars observed during three seasons by EROS (Expience de Recherche d'Objets Sombres), in the Galactic plane away from the bulge.
Journal ArticleDOI
Destriping of polarized data in a CMB mission with a circular scanning strategy
TL;DR: In this paper, the authors investigated a method for building temperature and polarization maps with minimal striping effects in the case of a circular scanning strategy mission such as the Planck mission, where the scan-dependent orientation of the measured polarization was investigated.

TL;DR: In this article, the authors presented the results of a massive variability search based on a photometric survey of a six square degree region along the Galactic plane at (l = 305, b = 0:8 )a nd(l = 330 and b = 2:5).
