The evidence available so far has shown that a fuse in the primary power feed to the STIS blew, most likely the result of a short circuit somewhere between the fuse and the power convertors within the STIS. While we are still in the early stages of understanding what happened, we are hoping to fully restore STIS operations within the month of July. In the meantime, we believe we have an adequate pool of WFPC2 programs to maintain a good observing efficiency with HST. Error in "corrected times" using odelaytime with de200.fits The MJD in the header of de200.fits, the file which describes the Earth's ephemeris, is off by 0.5 days. This causes an error in the barycentric correction to the time stamps when using "odelaytime" with the STIS timetag data. We provide here the IRAF commands needed for you to fix the de200.fits file. +-----------------------------------------------------+ | Need help? | | http://www.stsci.edu/cgi-bin/stis?cmd=help | +-----------------------------------------------------+ | 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. | +-----------------------------------------------------+
