POKER:使用复杂掩模和高角分辨率估计漫发射的功率谱

POKER: Estimating the power spectrum of diffuse emission with complex masks and at high angular resolution

Nicolas Ponthieu, Julien Grain, Guilaine Lagache

摘要:

我们描述了一个角功率谱估计器在平天近似的实现。POKER(P. Of k EstimatoR)基于Hivon及其合作者在CMB各向异性背景下开发的MASTER算法。它完全工作在离散空间,可以应用于任意高角分辨率地图。因此,它特别适合于当前和未来的红外到亚毫米观测漫射发射,无论是银河系还是宇宙学。

英文摘要:

We describe the implementation of an angular power spectrum estimator in the flat sky approximation. POKER (P. Of k EstimatoR) is based on the MASTER algorithm developped by Hivon and collaborators in the context of CMB anisotropy. It works entirely in discrete space and can be applied to arbitrary high angular resolution maps. It is therefore particularly suitable for current and future infrared to sub-mm observations of diffuse emission, whether Galactic or cosmological.
