|WFC3 Data Handbook v. 3.0|
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.
Information especially likely to be updated on the WFC3 website is indicated by this symbol.
