The HEASARC WWW Offerings

What's New

Like the HEASARC gopher server, its WWW server is relatively new. New documents and capabilities are being added at an ``astronomical" (har har) rate. The ``What's New" link provides the user with an up-to-date list of recently added information and services.

General Information

This link provides general information about the organization of the HEASARC and its activities.

HEASARC Groups and Affiliated Organizations

The HEASARC home page provides access to the Guest Observer Facilities (GOFs) for the ROSAT, ASCA, CGRO, and XTE missions. Each GOF has its own home page, which gives access to mission-specific information and news. The GOF home pages give users news updates on the status of mission operations, software releases, and proposal deadlines. On-line versions of the most recent issues of the ROSAT Newsletter and ASCANews also are available from the GOF pages. In addition, these home pages link directly to each mission's area of the anonymous ftp and gopher servers. In addition to the GOF home pages, the HEASARC home page is linked to the Astrophysics Data Facility (ADF). The ADF provides users with updates on the status of data processing for a variety of missions. One can select a specfic mission from the ADF home page, or link to the mission's data center via the GOF home page.

The HEASARC Calibration Database

This link is a ``jumping off" point for calibration data sets, software and documentation. It also links to the ``caldb" directories of the ftp and gopher servers, as well as to each of the GOF home pages.

High Energy Astrophysics Meetings

This link is a regulary-updated list of meetings pertaining to High Energy Astrophysics. Each meeting in the list is linked its announcement and further details.

High Energy Astrophyics Missions

The High Energy Missions link lists past, current, and future missions in high energy astrophysics. Each mission has a summary of the its instrumentation, specific features, and science. In the future, this list will provide links to more detailed information on each mission as well as to a mission bibliography.

Images of High Energy Astrophysics

Users interested in seeing the results of some high energy astrophysics missions can select the ``Images" link. This link is to color images obtained from past and current missions, as well as to the ROSAT CD ROM images.

Staff

The Staff link contains a listing of HEASARC staff, divided by mission and by specialty. The list is linked to short bios and contact information for each staff member.

HEASARC Information Services

In addition to the WWW, the HEASARC provides a number of other information services. This link provides a gateway to services such as the ftp and gopher servers. It also allows users to login to the xray account and run BROWSE from the WWW, and to perform e-mail searches of the HEASARC databases. Moreover, users can access information about subscribing to the HEASARC's many mailing lists, and get month-by-month usage statistics for the HEASARC's WWW, ftp, and gopher servers.

Navigating the HEASARC Web

The user will notice small, clickable ``buttons" on each of the HEASARC WWW pages. These buttons were designed to provide easy navigation within the HEASARC Web. For example, at the top of each page is a set of buttons that indicates where in the HEASARC ``tree" the page lies. Each button provides a link to the pages higher up the tree. At the bottom of each page are a standard set of buttons that link to common ``jumping off" pages for the HEASARC. Pages also may contain buttons linking the user to pages that precede or follow the current page in a specific ``weblet."
