Getting Help

Quick help: If you are uncertain about command syntax, typing a command preceded or followed by a “?” will print a short summary. The help command:

XSPEC12> help

without arguments will bring up the full XSPEC manual in a PDF document reader (e.g. AdobeTM Acrobat Reader), or will open a browser to the XSPEC manual home page either locally or on the HEASARC site. See “Customizing XSPEC” later in this chapter to see how to select between these options, and how to assign a PDF reader and web browser to XSPEC. Typing

XSPEC12> help <command>

will display the manual section corresponding to $<$command$>$. Help for individual model components can be displayed by

XSPEC12> help model <modelName>

If all else fails you can e-mail your questions to the XSPEC team at
