Synopsis

Schechter function. Integration OFF.

Description

An integrated 1-D Schechter model:

f(x_i) = A (x_i/x_ref)^alpha exp(-x_i/x_ref) [x_(i+1) - x_i]/x_ref

SCHECHTER Parameters

Number Name Description
1 alpha power coefficient alpha
2 ref reference value x_ref
3 norm normalization factor A
