2nd Chandra/CIAO Workshop Hands-on Session

April 2001 Workshop Index

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/
