2nd Chandra/CIAO Workshop Hands-on Session

For the second Chandra/CIAO workshop, we have modified the format of the hands-on session. Each day will begin with instructional talks and the afternoon will be reserved for hands-on practice.

Practical Information:

• There are 15 workstations called "DEMO1, DEMO2, ... DEMO15." With 30 people registered for the workshop, two people need to work at each computer.
• Users should log-in as "cxcguest1", "cxcguest2", etc. on the corresponding machines. The passwords will be revealed on Monday.
• All the "cxcguest" accounts are already setup to run CIAO2.1. On every window where you expect to run CIAO, you should simply type "ciao". For example:

  cxcguest-1: ciao
  CIAO configuration is complete... 
     version   :  CIAO 2.1 Wednesday, February 28, 2001
     bin dir   :  /soft/ciao/bin
  

• Some useful checks:

  cxcguest-2: ciao -v
   This script sets the user's CIAO environment to utilize:
   version   :  CIAO 2.1 Wednesday, February 28, 2001
   bin dir   :  /soft/ciao/bin
   The current environment is already configured for:
   version   :  CIAO 2.1 Wednesday, February 28, 2001
   bin dir   :  /soft/ciao/bin
  
  cxcguest-3: echo $PFILES
  /home/cxcguest/cxcds_param;/soft/ciao/param
  
  cxcguest-4: echo $CALDB
  /soft/ciao/CALDB
  
  cxcguest-5: echo $ATOMDB
  /soft/ciao/ATOMDB
  

• The workspace is in
  /data/ciao_demo/
  15 subdirectories have been created called cxcguest1 through cxcguest15; please use the one relative to your machine.
• Chandra data useful for the analysis can be found in
  /data/ciao_demo/threads
• All the CIAO scripts are already downloaded in
  /soft/ciao/bin
  and can be called from the command line.
• If you need to access CALDB files, they are in
  /soft/ciao/CALDB, which is linked to /data/CALDB/
• If you need to access ATOMDB files, they are in
  /soft/ciao/ATOMDB, which is linked to /data/axaf8/atomdb/
