INT/WFC北方银道面Hα测光巡天（IPHAS）是利用2.5米艾萨克·牛顿望远镜（INT）上的宽视场照相机（WFC）在r ′= 20（10σ）深度处进行的Hα、r′ andi′滤光片成像巡天。该调查旨在揭示银河系的大规模组织，并可用于识别银河系内的一系列恒星种群。绘制发射线天体可以特别关注恒星演化的年轻和年老阶段的天体，从早期的T-Tauri恒星到晚期的行星状星云。在本文中，我们提出了IPHAS的初始数据发布，主要是一个测光目录约200万个独特的对象，再加上相关的图像数据，覆盖约1600 deg 2在三个通带。我们注意到如何通过使用标准的虚拟天文台发布接口来实现对原始数据产品的访问。除了一些直接相关的共同目录（如2 MASS）外，还提供了对IPHAS主要测光目录的简单传统网络访问。通过AstroGrid虚拟天文台桌面访问开放了全方位的分析选项，并允许与虚拟天文台提供的更广泛的数据和服务完全集成。IDR代表了迄今为止主要通过VO接口发布的最大数据集，因此可以作为调查数据挖掘未来的典范。数据访问的例子，包括交叉匹配的IPHAS测光与源在UKIDSS银河平面调查，验证现有的校准的最佳数据。
The INT/WFC Photometric Hα Survey of the Northern Galactic Plane (IPHAS) is an imaging survey being carried out in Hα,r′ andi′ filters, with the Wide Field Camera (WFC) on the 2.5-m Isaac Newton Telescope (INT) to a depth ofr′= 20 (10σ). The survey is aimed at revealing the large scale organization of the Milky Way and can be applied to identifying a range of stellar populations within it. Mapping emission line objects enables a particular focus on objects in the young and old stages of stellar evolution ranging from early T-Tauri stars to late planetary nebulae. In this paper we present the IPHAS Initial Data Release, primarily a photometric catalogue of about 200 million unique objects, coupled with associated image data covering about 1600 deg2in three passbands. We note how access to the primary data products has been implemented through use of standard virtual observatory publishing interfaces. Simple traditional web access is provided to the main IPHAS photometric catalogue, in addition to a number of common catalogues (such as 2MASS) which are of immediate relevance. Access through the AstroGrid VO Desktop opens up the full range of analysis options, and allows full integration with the wider range of data and services available through the Virtual Observatory. The IDR represents the largest data set published primarily through VO interfaces to date, and so stands as an exemplar of the future of survey data mining. Examples of data access are given, including a cross-matching of IPHAS photometry with sources in the UKIDSS Galactic Plane Survey that validates the existing calibration of the best data.
