                            ===================
                              MAGELLAN IMAGES
                              June 19, 1991
                            ===================

     I've placed 17 more Magellan images at the Ames SPACE archives, bringing
the Magellan total to 36 images.  These new images are in VICAR format which is
the format used at the Image Processing Lab (MIPL) at JPL.  The images are
obtainable via anonymous ftp from ames.arc.nasa.gov (128.102.18.3), and are in
the pub/SPACE/VICAR directory.  All of the Magellan images I've put at the
Ames site are public release images from the Magellan project, and are in the
public domain and can be freely distributed.  These new images are *not* on the
first Magellan CDROM released earlier this year.

     The new Magellan files and their sizes are:

          alcott.img       1,049,600 bytes
          ammavaru.img     1,312,000 bytes
          arachcom.img       971,880 bytes
          barton.img       2,626,020 bytes
          flows.img        3,616,434 bytes
          golubnew.img     1,025,145 bytes
          golubold.img     1,025,145 bytes
          gulamons.img       914,328 bytes
          hestia.img       1,422,603 bytes
          lakshmif.img       822,584 bytes
          mead.img         1,312,000 bytes
          navka.img        2,521,800 bytes
          ovda.img         1,180,310 bytes
          pandora.img        918,528 bytes
          sifflows.img       621,600 bytes
          test25pvo.img    1,006,304 bytes
          test25rm.img     1,006,304 bytes

     All of the VICAR images have a corresponding caption files (with a .txt
extension) which contains detailed descriptions of the image.  Make sure
you are in binary mode when transferring the image files, and in ASCII mode
when transferring the txt files.

     The VICAR images can be viewed on an IBM PC computer with the IMDISP
program stored in a zip file called imdisp56.zip, located in the
pub/SPACE/SOFTWARE directory, at the same Ames site.  IMDISP is the same
program distributed with the Voyager and Magellan CDROMs.  Since I am one of
the programmers for IMDISP, I would welcome any feedback on IMDISP, including
any problems encountered with its use or suggestions on improving the program.
A new version of IMDISP will be released in a about a couple of weeks; I'll
post an an announcement when it is ready.

On convex.com [130.168.1.1] can be found pub/xl.3.0.1.patches.Z, which is
a compressed shar archive containing a couple of new files and some patches
to xloadimage version 3.0.1.  The patches are largely for speed.  The new
files allow xloadimage to view 8-bit VICAR and PDS files.  Both the Huffman-
encoded and unencoded variants of the latter are handled.  These Magellan
images are examples of VICAR.  The files on the Voyager CD-ROMS are examples
of both variants of PDS.
