    workshop guide used at the AAPT winter 2006 meeting: learn how to use ds9 in an hour or less!
    similar presentation made at the HOU TRA 2005 conference in Williams Bay, WI

ds9: frequently asked questions  (in progress)

how to find & download Chandra images for use with DS9

    how to find an image of a certain object; how to browse the image directory;
    how to download an image for use with the image processor ds9;
    how to unzip the compressed images

decoding the x-ray spectra of supernova remnants

    sample supernova remnant spectra with line identifications;
    how-to guide for identifying emission lines in supernova spectra;
    how to determine the temperature of a remnant by modeling the continuous spectrum
    how to make 3-color JPG images with different colors representing different elements

light curves, periodicities, & power spectra:

   a guided study of the Cen X-3 system

    how to find periodicities in x-ray variable sources using light curves and power spectra
    a version of the Clocks in the Sky Chandra activity (for Cen X3), originally written by Terry Matilsky
    how to use power spectra to determine the orbital speed of a pulsar (or other periodic source) in a binary

the astrophysics of short-period luminosity variations

    periodic phenomena (binaries, pulsation, rotation);
    how to use periodicities to rule in or rule out various physical models;
    how to find masses of stars in binary system using periodicities

extrasolar planets & black holes: how astronomers find invisible objects   

    a tutorial on how invisible objects are discovered
   how to determine the mass and orbit size of extrasolar planets
   a worked example: determining the mass, orbital size, temperature, and composition of HD209458
   black hole publicly available data

short guide to selected FTOOLS commands  written by Ryan Pifer & Josh Wetherington

    (usable on a UNIX system where saoimage software has been installed)

    guide to unix commands
    guide to lcurve
    guide to powspec
    guide to fdump esearch efold
    guide to xselect

labs, activities, & results

Chris Vo's analysis of the expansion rate & age of Cas A
watch Cas A expand with his animated gif

superluminal motion in 3C273
(an addendum to the Chandra 3C273 activity 6)

    understanding the apparent superluminal motion of the 3C273 jet;
    determining the actual speed of the jet from the observations;
    requires knowledge of special relativity and calculus

classroom-ready image processing activities
    (written for a high school or college audience)

    these do not necessarily involve Chandra images

not related to Chandra or image processing

comet stuff: 
are energy and angular momentum conserved as a comet orbits ?

the origin of comets
:  Kuiper belt or Oort cloud or elsewhere?

    not sure what this has to do with Chandra but the writing of these happened
        as a result of the Chandra Resource Agent conference in 2004;
    feedback welcome
    the conservation activity requires use of spreadsheets and contains some calculus;
    the origin of comets activity does not use calculus, although spreadsheet knowledge would be helpful;
    both activities presume some knowledge of physics and familiarity with ellipses and orbits

the black hole at the center of our galaxy

    observational data, sample measurement, physics equations, graphical analysis of dat:
    written for teachers; selected portions can be given to your students for homework, projects,. etc

assorted info & software

how to get around proxy servers and firewalls when using DS9 and VNC

    if your school runs a proxy server or has a firewall, adjustments may be necessary in order for ds9 to work properly

a selected list of x-ray telescopes

    links to telescope sites and telescopes properties (e.g., spatial resolution, energy range)

download VNC
