4th Chandra/CIAO Workshop Hands-on Session

Practical Information:

• There are 12 workstations available -- DEMO1, DEMO2, ... DEMO12. With 25 people registered for the workshop, everyone will need to work in pairs.
• Users should log in as cxcguestx where x is the machine you are on; i.e. the user on DEMO1 is cxcguest1 ... DEMO2 is cxcguest2. The passwords will be revealed Monday afternoon.
• All the accounts are already set up to run CIAO2.2.1. On every window where you expect to run CIAO, you should simply type ciao:

  unix% ciao
  Warning: Not fully tested version of Solaris
  Warning: CIAO has not been fully tested on this system
  CIAO configuration is complete... 
   CIAO version     :  CIAO 2.2.1 Tuesday, December 4, 2001
   Proposal Toolkit version :  NRA 4.0 Monday, December 10, 2001
   bin dir          :  /soft/ciao/bin
  

  The warning is issued because CIAO 2.2.1 has not been fully tested in Solaris v2.8, which this machine is running.
• Some useful checks:

  unix% ciao -v
   The current environment is already configured for:
   CIAO version     :  CIAO 2.2.1 Tuesday, December 4, 2001
   Proposal Toolkit version :  NRA 4.0 Monday, December 10, 2001
   bin dir          :  /soft/ciao/bin
  
  unix% echo $PFILES
  /home/cxcguest1/cxcds_param;/soft/ciao/param
  
  unix% echo $CALDB
  /soft/ciao/CALDB
  

• The workspace is in /data/ciao_demo/. 15 subdirectories have been created called cxcguest1 through cxcguest15; please work in the one relative to your machine. A link to this location has been set up in the home directory of each account:

  unix% pwd
  /home/cxcguest1
  unix% cd workshop/
  unix% pwd
  /data/ciao_demo/cxcguest1
  

• Chandra data used in the analysis threads can be found in /data/ciao_demo/threads/. A link to this location has been set up from the workspace:

  unix% pwd
  /data/ciao_demo/cxcguest1
  unix% ls -l
  total 0
  lrwxrwxrwx   1 cxcguest1      11 Nov  2 14:21 data -> ../threads/
  
  unix% ls data/
  Chips           Sherpa          acisletg        hrcsletg
  Detect          acis-i          hrc-i
  GUIDE           acis-s          hrc-s
  S-Lang          acishetg        hrciletg
  

  The CIAO tools accept paths as part of the input file names, so it is not necessary to copy all the data to your working directory. You may also set up symbolic links to access the data.
• We have already downloaded all the CIAO scripts. This means that they can be called from the command line in the same manner as the CIAO tools:

  unix% which ciaover
  /soft/ciao/contrib/ciaover
  
  unix% ciaover
  
  CIAO version: CIAO 2.2.1
  CIAO series: CIAO2
  Current directory is writeable
  DM tools found in /soft/ciao/bin
  DM library found in /soft/ciao/lib
  

  If a script is missing or seems outdated, it may be downloaded from http://cxc.harvard.edu/ciao/download_scripts.html
