This and previous issues of the STAN can be found at http://www.stsci.edu/hst/stis/documents/newsletters. +----------------------------------------------------------+ Time Dependent Sensitivity Corrections for CCD First-Order Spectroscopic Modes Reference files have now been delivered that allow CALSTIS to correct CCD first-order spectra for the degradation of the throughput of the STIS optics over time. At the shortest wavelengths covered by the G230LB, these corrections can amount to nearly 2% per year. Incorrect PDF version of STIS Instrument Handbook published An incorrect PDF version of the STIS Instrument Handbook was released on 2003-Oct-6. One of the most important sections for HST proposers, Chapter 2 - "Special Considerations for Cycle 13," was among the sections not fully updated in the PDF document. If you downloaded the PDF version between Oct. 6th and Nov. 18th, you should re-download the correct version now. +----------------------------------------------------------+ | Need help? http://www.stsci.edu/hst/stis/help.html +----------------------------------------------------------+ | To subscribe or unsubscribe to the STAN, send a message | to majordomo@stsci.edu with a blank subject line and | the following in the body: [un]subscribe stis_news +----------------------------------------------------------+ | The Space Telescope Science Institute is operated by the | Association of Universities for Research in Astronomy, | Inc., under NASA contract NAS5-26555. +----------------------------------------------------------+
