Online Astronomical Resources
• Catalogs (Database tables)
• Image archives
– Spectrum archives
• Bibliographic archives
• Information services

SkyMouse: A light-weight
information collector
• Not like some VO efforts on uniformed
access systems, for example, NVO
DataScope, SkyMouse tries to show a
comprehensive overview for a specific
object, but not to snatch as much data
as possible.

Characteristics
• Easy of Use. Access to world wide astronomical references,
catalogs, images, and maybe more, by a simple “MouseOver”
action.
– Traditional query system: Copy your words->Open
Web Browser>Visit Astronomical Database website>Select service->Paste->Custom Options->Submit
– SkyMouse: Mouse over or select -> Click “SkyMouse” icon

Functions
• Two use mode: through SkyMouse client or use the server
directly.
• Three capture mode: screen, select (recommended), and
hot key.
• PDF support (select mode only).
• Multiple types of backend services integration, HTTP GET,
CGI, Web Services, Grid Services.
• Update check.
• Per-selected commonly used resources including SIMBAD,
DSS, ADS, VizieR and NED.
• Simple services custom by user

Technic Highlights
• “Screen character capture” technic
developed independently.
• Web 2.0 technologies:
– AJAX, provides smoothly response and better
user experience.
– .Net framework, the backend system is based
on MicroSoft .Net framework.
– Web Services, most components in the backend
are Web Services.

How the SkyMouse works?
• Characters on the screen are captured by the
client, then will be sent to SkyMouse server after
simple analyse. SkyMouse server accepts item
from the client and then sends it to name
resolving service of SIMBAD or NED for further
information, esp. coordinate. Different
databases will be queried using the coordinate
and object name. SkyMouse server collects
results and displays them in user’s default web
browser.

SkyMouse
• A new user interface for Astronomical
online services
• An intelligent VO client
• A commodity for astronomers and students

We need your help on…
• How to know the captured words is an
astronomical object?
• How to give a better layout for the large
queried result?
