APERO: A PipelinE to Reduce Observations—Demonstration with SPIRou
نویسندگان
چکیده
Abstract With the maturation of near-infrared high-resolution spectroscopy, especially when used for precision radial velocity, data reduction has faced unprecedented challenges in terms how one goes from raw to calibrated, extracted, and corrected with required precisions thousandths a pixel. Here we present A PipelinE Reduce Observations ( apero ), specifically focused on Spectro Polarimètre Infra ROUge (SPIR ou spectropolarimeter Canada–France–Hawaii Telescope (SPectropolarimètre InfraROUge, CFHT). In this paper, give an overview detail procedure SPIR . delivers telluric-corrected 2D 1D spectra as well polarimetry products. enables precise stable velocity measurements sky (via LBL algorithm), which is good at least ?2 m s ?1 over current 5 yr lifetime

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

Voting is a fundamental part of any democratic society. But survey based measures of voting are problematic because a substantial proportion of nonvoters report that they voted. This overreporting has consequences for our understanding of voting as well as the behaviors and attitudes associated with voting. Relying on the “bogus pipeline” approach, we investigate whether altering the wording of...

متن کاملa new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
