本文介绍由业余天文学家发起的自主窄带 Hα 全天成像巡天 MDW 的首次数据发布 DR0,公布猎户座区域238个天区的校准图像、恒星移除图像、匹配点源星表及拼接图。

摘要:

Mittelman-di Cicco-Walker(MDW)Hα 天空巡天是一项在窄带 Hα 波长开展、自主运行且仍在进行中的全天成像巡天。该巡天由业余天文学家创立,本文介绍其面向严格科学用途的第一阶段精化成果。每个天区通过带宽为3 nm的 Hα 滤光片曝光总计4小时,像素尺度为3.2角秒。在此,我们介绍 MDW Hα 巡天的首次数据发布(Data Release 0,即 DR0),覆盖猎户座区域的238个天区(约3100平方度)。DR0包括:经过校准的平均天区图像、移除恒星后的平均天区图像、与 Pan-STARRS1(全景巡天望远镜与快速响应系统第1次数据发布)和 IGAPS(INT银道面巡天)匹配的点源星表,以及拼接图。

英文摘要:

The Mittelman-di Cicco-Walker (MDW) H$α$ Sky Survey is an autonomously-operated and ongoing all-sky imaging survey in the narrowband H$α$ wavelength. The survey was founded by amateur astronomers, and is presented here in its first stage of refinement for rigorous scientific use. Each field is exposed through an H$α$ filter with a 3nm bandwidth for a total of four hours, with a pixel scale of 3.2 arcsec. Here, we introduce the first Data Release of the MDW H$α$ Survey (Data Release 0, or DR0), spanning 238 fields in the region of Orion (~3100 deg$^2$). DR0 includes: calibrated mean fields, star-removed mean fields, a point source catalog matched to Data Release 1 of the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS1) and the INT Galactic Plane Survey (IGAPS), and mosaics.
