This and previous issues of the STAN can be found at http://www.stsci.edu/hst/stis/documents/newsletters. +----------------------------------------------------------+ New STIS Target Acquisition Checking Procedure As of May 9th, manual checks of STIS target acquisitions are no longer being performed on a daily basis. ACQ and ACQ/PEAK data will now be reviewed monthly, and the PI or designated contact will receive a warning by email at that time if there appear to be problems with the acquisition. New version of "daydark" script available We have updated the IRAF/STSDAS task "daydark", which is available in the stsdas.hst_calib.stis package to create CCD dark reference files with a "daily" update of the hot pixels. We have made the new script available immediately through the STIS web pages, and it will be part of the upcoming STSDAS release. The 2002 HST Calibration Workshop The 2002 HST Calibration Workshop will be held on October 17 and 18 at the Space Telescope Science Institute in Baltimore, Maryland. The program will include invited oral talks, posters, and splinter sessions for current and retired HST instruments. All observers who have new ideas to contribute regarding the calibration of HST instruments are encouraged to present their work. How to add the "Proposed Aperture" name field to the StarView request form For a number of STIS apertures, it is possible to specify aperture names in the phase 2 proposal which put the target at different places within the same physical aperture. However, the value of the "Aperture" field in the STScI archive databases is always set to be the name of the *physical* aperture used. E.g., observations that specified 52X2E1 in the phase 2 proposal will still be listed in the archive as having used the 52X2 aperture. Learn how to perform a search in StarView for data which have a proposed aperture different from the physical aperture. +----------------------------------------------------------+ | 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. +----------------------------------------------------------+
