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/
