We'd like to take this opportunity to inform the user community about the great news that the recovery has been successful. STIS is in business again! Moving Targets: Ephemeris and Tracking Accuracies STScI currently uses the best planetary system ephemerides available from JPL. Observers of solar-system targets may wish to familiarize themselves with newly posted information on ephemeris and tracking accuracies. Change to CCD Imaging Throughput Calibration A significant change has been made to the adopted flux calibration for STIS/CCD imaging modes. STIS Web Site Redesigned The STIS Web site has been redesigned and updated. Check it out! Revised STIS Instrument Handbook for Cycle 11 A slightly revised version 5.1 of the STIS Instrument Handbook is now available. Version 5.1 includes an update of STIS operations in Chapter 2 and minor, but significant changes to the discussion of sky backgrounds and the Exposure Time Calculator in Chapter 6. +----------------------------------------------------------------------------------------+ | Need help? http://www.stsci.edu/hst/cos/help.html | +----------------------------------------------------------------------------------------+ | To unsubscribe from this mailing list send email to majordomo@stsci.edu | | with the message: unsubscribe stis_news | +----------------------------------------------------------------------------------------+ | The Space Telescope Science Institute is operated by the Association of Universities | | for Research in Astronomy, Inc., under NASA contract NAS5-26555. | +----------------------------------------------------------------------------------------+
