Preamble

The Space Telescope - European Coordinating Facility (STECF) is responsible for supporting the slitless spectroscopic modes of the Hubble instruments ACS and WFC3 until late 2010 with stdesk@eso.org as the main contact address.

After that time, all support (software, calibration and user support) will be provided by STScI Space Telescope Science Institute (STScI) with help@stsci.edu as the central contact.

The slitless spectroscopy URL's provided in this manual all point to www.stecf.org and below, and this web site will be kept up-to-date until late 2010.

Starting in 2011 the webpages for slitless spectroscopy will be hosted at: http://www.stsci.edu/resources/software_hardware/stsdas/axe/. Pages at www.stecf.org will reflect this and then point to the corresponding location at www.stsci.edu.
