This flag can be misleading. Read more. How do I know that wavecal processing worked correctly? Wavelengths in 1-D extracted spectra and 2-D rectified images will not be correct unless the offset of the Mode Select Mechanism (MSM) in the dispersion direction was successfully determined from the wavecal associated with the observation. Here are two things which can be checked to see whether there was a problem. STIS Calibration Outsourcing Opportunities for Cycle 10 There is a potential list of project candidates for Cycle 10 calibration outsourcing proposals that could be submitted in response to the Cycle 10 call for proposals. CALSTIS 2.6a Calstis version 2.6a was installed in the pipeline on May 9, 2000 and is also being used by OTFC. Calstis 2.6a will be available for download in a soon to be released version of STSDAS. There were two bugs corrected in this version. CALSTIS 2.6 Calstis version 2.6 was installed on Feb 14, 2000. Changes to CALSTIS in this version include a number of bug fixes, enhancements, and a number of new user tools and scripts. +-Spectrographs---------------------------------------+ Release of the Visual Target Tuner With the June Call for Proposals, STScI will release a prototype software tool called the Visual Target Tuner (VTT). This tool displays HST apertures superimposed on sky images. The VTT provides capabilities to import sky images, display primary and parallel apertures, rotate apertures, centroid objects, specify excluded points and regions, experiment with various orientations, and display catalog overlays and object information. List of Recent Preprints Now on Line The list of preprints based on HST spectrographs data that user to occupy this space is now available at http://www.stsci.edu/science/preprints/ for easy browsing. +-----------------------------------------------------+ | 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. | +-----------------------------------------------------+
