delta1d

Synopsis

1-D delta function.

Description

A 1-D delta-function model:

f(x) = A

if x = x_0, and

f(x) = 0

otherwise.

with

Int_(-Inf)^(+Inf) dx f(x) = A .

delta1d Parameters

The integration of models in Sherpa is controlled by an integration flag in each model structure. Refer to "ahelp integrate" for information on integrating model components.
