Sample Data for CSI 758

These data are located on the CSI science cluster @

science.gmu.edu

in directory

/usr/pub/beall/csi758/data

The files are available via a standard copy (cp) command

FITS DATA FILES:

A "FITS" (Flexible Image Transport System) file is stored in:

mex.fits
mex2.fits
temp.fits
temp3.fits

The data in this file are 16-bit (2 bytes) binary in a 512x512 array with some header information that is ASCII. They are an image of a galaxy, 3c390.3, in x-ray light.

HDF DATA

An HDF (Heirarchial Data File) file is stored under

brain.hdf

in order to give practice with volumetric rendering techniques

ASCII DATA
