1.6	The STIS Web Pages and Support Information

The STIS team at STScI maintains Web pages (see Figure 1.3) as part of STScI’s Web service. The URL for the top level STScI STIS Web site is:

http://www.stsci.edu/hst/stis

The STIS Web pages include up-to-date information about STIS operations and performance. Links to this information are organized into categories and sub-categories which are listed in a menu on the right hand side of all STIS Web pages. In addition to these main categories, a “shortcuts” list of links to frequently used resources can be found on this menu as well.

The main navigational categories are:

•	Instrument Design: A high-level summary of the basic design and operation of the Space Telescope Imaging Spectrograph (STIS), including summary information on the detectors, gratings, apertures, and filters available for use.

•	Performance: More detailed information on actual on-orbit performance of the STIS. Sub-categories are image quality, sensitivity, spectral resolution, throughput, background, accuracy, monitoring, and anomalies.

•	Observing Strategy: Discussions of target acquisitions, pushing the limits, and other aspects of the design of imaging and spectroscopic observations with STIS.

•	Proposing: Things you need to know in order to successfully construct and submit Phase I and Phase II proposals for STIS observations, and how to monitor the status of your observing program.

•	Data Analysis: Resources describing STIS data characteristics and analysis, including the STIS Data Handbook.

•	Software Tools: Planning and Analyzing: Software tools that can be retrieved (e.g., an IRAF script for creating daily dark reference files) or run directly over the network (e.g., the Exposure Time Calculators (ETC) and the Target Acquisition Simulator (TAS)).

•

Document Archive: Electronic versions of the Instrument and Data Handbooks as well as detailed technical information concerning the development, performance, testing, operation, and calibration of the STIS as documented in a series of STIS Instrument Science Reports (ISRs) and STScI Analysis Newsletters (STANs). These reports can be downloaded directly from the Web site.

•	Calibration: Information on STIS calibration plans and close-out reports for all cycles.

•	SMOV4: Description of the STIS plan for verification and preliminary calibration during SMOV4. Includes phase II proposal numbers and program titles.

•	Previous SMOV: Description of the requirements, plans, and implementation for SMOVs 2, 3a, 3b, and 4 for HST in general.
