    Shiftworkers crib sheets

    The links below give crib sheets for carrying out some standard procedures expected during run time. To modify the crib sheets copy the HTML file to your local disk (by right clicking the mouse on the link), then edit the HTML file. You can do this by either editing the raw HTML file in an editor (eg Xemacs) or by using a HTML editor (eg. Netscape composer). Then send the modified file as an attachment to d.watts@physics.gla.ac.uk and the updated crib will be put on the web server.
