|FGS Data Handbook|
To help you understand the material in this Data Handbook, we will use a few consistent typographic conventions.
• bold words identify an STSDAS, IRAF, or PyRAF task or package name.
• typewriter-like words identify a file name, system command, or response that is typed or displayed.
• italic type indicates a new term, an important point, a mathematical variable, or a task parameter.
• SMALL CAPS identifies a header keyword.Occasional side comments point out three types of information, each identified by an icon in the left margin.
Warning: You could corrupt data, produce incorrect results, or create some other kind of severe problem.
Tip: No problems...just another way to do something or a suggestion that might make your life easier.
