Look for a subdirectory with the date of the observations. This directory
contains the original ``fits'' image files, and a file of notes that
describe each image.
These systems run Linux and have a ``Gnome'' user interface, so there will be a familiar looking graphical screen with icons available. Most work with Linux or Unix is done from the command line, so begin by opening a ``Console'' into which you can type commands. The icon for a console is the image of a computer screen on the top bar. It may have a large X on it as well. Double click this icon and a console window should appear. If you want more than one window, just do this again. You also have four ``workspaces'' available represented by the small images at the bottom right. Click on one these if you need an uncluttered screen. Linux is multi-tasking and you may do several things at once.
Here are a few help commands that can be typed into the console screen that you may need:
cd
change directory
mkdir
create a directory
ls
list files in the directory
ds9
display images
fits_subtract
subtract two images
gimp
manipulate appearance of images
xephem
interactive ephemeris displays the sky
xmccd
run a scientific ccd camera
xmtel
run a telescope
cd /home/astrolab/moore/20041106
where ``20041106'' was the
date of the observation. There may be more than one date, and if that is the
case, then repeat this for the other dates to put all of the raw data into your
own working directory.
cp * /home/astrolab/myimages/
where
``myimages'' is the directory you created above.
