Description: 

This new data set consists of pixel map data (DATA) in ascii format, GIF 
image, and postscript (PS) image files for sky maps accummulated from 
neutral gas particles measured by the neutral gas (GAS) experiment on 
Ulysses. There are three types of sky maps in the corresponding 
subdirectories: (1) full sky, (2) interstellar helium, and (3) Jupiter. 
The counts and coordinates of each sky map pixel are given in the pixel 
map files in the DATA subdirectories,  while the full images are provided
in GIF and postscript (PS) format, respectively in the GIF and PS 
subdirectories.  The GIF files are most easily viewed with a web browser
like Netscape or Internet Explorer. The files ULYGAS_GUIDE.txt, 
ULYGAS_FORMAT.txt, and ULYGAS_REF.txt respectively give an overall 
description of the various datatypes, the record format for the DATA 
datatype, and a list of GAS-related publications.  Further details on the
GAS experiment and data may be found in the NSSDC Master Catalog via the 
Ulysses flight project page (see below) and in the GAS instrument papers 
in the ULYGAS_REF.txt file.
