AVO prototype and CDS tools 高丹 LAMOST
内容 天文物理方法介绍和天文需求 总述并简单介绍Simbad、VizieR查询工具 从功能角度介绍AVO prototype 总结&思考
AVO Science AVO has produced REAL science tools, which can be (and are!) used for astronomical research: AVO prototype is a very flexible toolset with plug-ins which allows easy access to images, spectra, and catalogues ASTROGRID’s workflow builder and MySpace are at cutting edge of VO development Interaction between astronomers and developers has been extremely good and beneficial to everybody
AVO partner ESO, Germany Space Telescope - European Coordinating Facility (ST-ECF), Germany The ASTROGRID (UK) Consortium CDS, France CNRS - Delegation Paris A (CNRSDR01-Terapix), France The Victoria University of Manchester (UMAN-Jodrell Bank), England
CDS
The 3 main services SIMBAD VizieR Aladin
Aladin for AVO prototype Image re-sampling(filter) （预处理、分析） Query by list –SIMBAD, VizieR （查询） Cross-match tool （预处理、分析） VO-plot （分析） Plugin for Specview （光谱处理） and VOSpec （光谱分析） Dist （天体测量）
两个示例 Filters are an elaborated feature in Aladin allowing one to customize the display of catalogue planes in Aladin. $[PHOT_JHN_J]<14 { draw green square } cross-match tool Vo-plot
Specview 显示（Displaying） 测量（measuring） 处理（processing） 拟合（fitting）
Vo-spec Get spectra from SSA servers Display and superimpose spectra Automatic unit conversion Multi-wavelength analysis Polynomial/Black body/Gaussian fitting
Estimation of the proper To measure the distance between two epoch positions: use the distance button and drag a double arrow with the left button of your mouse between the 2 points.
