From levay@stsci.edu Mon Sep 27 13:32:56 1993 Newsgroups: sci.astro From: levay@stsci.edu (Zoltan Levay) Subject: HST PR Images via ftp Originator: levay@lithops.stsci.edu Organization: Space Telescope Science Institute Date: Fri, 24 Sep 1993 18:00:47 GMT HOW TO RECEIVE HUBBLE SPACE TELESCOPE IMAGES ELECTRONICALLY The Space Telescope Science Institute's Educational and Public Affairs Office offers an electronic news service which makes Hubble Space Telescope public release images available electronically as part of the STScI Electronic Information Service (STEIS). Downloading the images requires that you have access to an Internet host computer that supports Anonymous File Transfer Protocol (FTP). Call the STEIS bulletin board by typing: "ftp stsci.edu". The following example illustrates a typical session. Note that various ftp programs may differ in the specific interaction, but the commands will be similar. prompt "STSCI.EDU>" - enter "login" prompt " FOREIGN USERNAME: " - enter "anonymous" prompt "PASSWORD: " - enter "[your last name]" - enter "cd stsci/epa/tiff" (or gif) - enter "dir" (List image file names) - enter "binary" (Set transfer mode) - enter "get [image file]" (Retrieve a file) Under the directory "epa", there are two subdirectories containing HST images in different formats. The "gif" directory contains images in GIF format which supports up to 256 colors (8-bits per pixel). The "tiff" directory contains images in TIFF format, which supports full color (24-bits per pixel). All image data are binary, so when transferring using ftp, make sure to set the transfer mode to "binary". Both image directories include plain (ASCII) text files containing descriptions of the images. In addition, there are README files which describe the contents generally, and Index files which give a bit more information on each image. ************************************************************* /stsci/epa/gif as of September 1993 File Name Size Instrument Object --------- ---- ---------- ------ fortuna.gif 614x346 PC Asteroid 19 Fortuna m31c.gif 1132x769 M31 galaxy composite mars.gif 512x512 WF/PC Mars, composite color marsb.gif 512x512 WF/PC Mars, blue frame marsg.gif 512x512 WF/PC Mars, green frame marsr.gif 512x512 WF/PC Mars, red frame ngc1741.gif 849x615 FOC NGC 1741 starburst in galaxies ngc2440.gif 700x700 WF/PC NGC 2440 ngc4261.gif 459x427 WF/PC NGC 4261 galaxy ngc6624.gif 466x243 FOC NGC 6624 globular cluster ngc7252.gif 512x512 WF/PC NGC 7252 (Atoms for Peace Galaxy) orib.gif 680x524 WF/PC Orion Nebula, blue frame orig.gif 680x524 WF/PC Orion Nebula, green frame orir.gif 680x524 WF/PC Orion Nebula, red frame /stsci/epa/tiff as of September 1993 File Name Size Instrument Object --------- ---- ---------- ------ cloop.tiff 1519x1526 WF/PC Cygnus Loop nebula jupiter.tiff 800x800 WF/PC Jupiter m31.tiff 340x290 WF/PC M31 Nucleus m31c.tiff 1132x769 M31 galaxy composite m51.tiff 512x512 M51 galaxy mars.tiff 512x512 WF/PC Mars mb3.tiff 175x133 ngc2300.tiff 285x340 ROSAT NGC 2300 galaxies ngc4261.tiff 795x631 WF/PC NGC 4261 galaxy ngc5728.tiff 669x515 WF/PC (PC) NGC 5728 Seyfert galaxy ngc6624.tiff 1024x683 X-ray burster illustration ngc7252.tiff 512x512 WF/PC NGC 7252 galaxy odellcoll.tiff 557x406 Orion Nebula oria.tiff 680x524 Orion Nebula orib.tiff 803x603 Orion Nebula oric.tiff 1142x858 Orion Nebula oricomp.tiff 1600x1600 Orion Nebula rosat5.tiff 285x340 ROSAT NGC 2300 galaxies saturn.tiff 546x492 WF/PC Saturn -- Zolt levay@stsci.edu
