WebSpec Home Page - Advanced Interface

Okay, I already think I am going to need HELP!

WebSpec is a WWW interface for the X-ray spectral fitting package, XSPEC. It simulates spectral data for a variety of X-ray missions/instruments. WebSpec can not be used to analyze real data.

Choose a Mission/Instrument

Specify the desired model expression by clicking on the proper combination of components and operators. When you are ready click the button to set model parameters. To start again click the reset button.

Some examples:	*Photoelectric Absorption Meka**
	*Photoelectric Absorption ( Power Law + Gaussian )**
	*Photoelectric Absorption ( Gaussian + Black Body + Photoelectric Absorption (Power Law) )*

Component 1	Component 2	Component 3
Component 4	Component 5	Component 6
Component 7	Component 8	Component 9

Okay, I have read this page but I still need HELP!
