MOSAIX:从GALEX图像构建大型马赛克的工具

MOSAIX: a tool to built large mosaics from GALEX images

Marcelo Armengot, Nestor Sanchez, Javier Lopez-Santiago, Ana Ines Gomez de Castro

摘要:

大型巡天为研究星际介质、银河系结构或宇宙网提供了大量信息。这种研究需要将来自不同波长、大视场的信息设置到一个公共帧中。GALEX是唯一一个几乎全天紫外线波段的观测项目,包含各种研究的基本信息。GALEX的视场是圆形的,嵌入在一个3840 x 3840像素的正方形矩阵中。这一事实使得GALEX图像很难与现有的天文工具(如Aladin或Montage)正确重叠。我们为此开发了自己的软件。在这篇文章中,我们描述了这个软件,并将其提供给社区。

英文摘要:

Large sky surveys are providing a huge amount of information for studies of the interstellar medium, the galactic structure or the cosmic web. Setting into a common frame information coming from different wavelengths, over large fields of view, is needed for this kind of research. GALEX is the only nearly all-sky survey at ultraviolet wavelengths and contains fundamental information for all types of studies. GALEX field of view is circular embedded in a squared matrix of 3840 x 3840 pixels. This fact makes it hard to get GALEX images properly overlapped with the existing astronomical tools such as Aladin or Montage. We developed our own software for this purpose. In this article, we describe this software and makes it available to the community.
