... We report on the development of a Web agent which allows users to conveniently find information about specific objects or locations from astronomical resources on the World Wide Web. The HEASARC Astrobrowse agent takes a user-specified location and queries up to hundreds of resources on the Web to find information relevant to the given target or position. ... The types of resources the user can get include images, name resolution services, catalog queries or archive indices. ...

... TEXAS SURVEY: THE PRELIMINARY -35 and stronger than 0.25 Jy is intended to provide accurate (one arc-second rms error) positions, flux densities and structure models for each of the ~70000 sources expected to be listed. ... Average rms position accuracy for point sources is 1" in RA and 0.5" in DEC. ... 1 is the source name in IAU format. ... Thus, (+1,+1) means the second most likely lobe is 51.8" LATER in RA, and 51.8"*sec(z) HIGHER in DEC than the position listed. ...

Region markers can be moved, resized, rotated, zoomed, deleted, and can change geometric type. ... For example, markers placed on astronomical catalog positions should be fixed so that one cannot accidentally move them off the specified position. ...
