How to Start CAOBS

CAOBS will normally already be running before you start observing. However if it isn't, perform the following steps to restart CAOBS:

Check that CACOR is running. (The CACOR GUI is usually displayed next to the PERICLES terminal that CAOBS is run from.) CACOR needs to be started before CAOBS. If it is not, start CACOR as described in section 8.3.1.

On PERICLES, locate the yellow/black CAOBS window and ensure that this window displays the normal xbones $ prompt.

Ensure that CACOR is happy. It should contain messages to the effect that that observations have stopped and the data file is closed.
CHECK for the messages FITS file closed in the STATE panel of CACOR.

XBONES$ caobs

To restart CAOBS.

Wait about one minute while CAOBS refers to its database and initialises.

There is currently (October 2006) a problem with CAOBS that affects the very first scan after caobs starts. To avoid problems with correlator error messages or strange delay jumps, please stop the first scan after a few cycles and restart it. Something like,

set file my_schedule

track 1

stop

track 1

should do the trick.

In the unlikely event that this does not resurrect CAOBS, use the up arrow to find the last command that started CAOBS, or: XBONES$ run at$run:caobs

If it still won't start, refer to CAOBS does not start
