A constant model for two-dimensional data.
This is a specialized form of the Const2D model where the integrate flag is turned off.
>>> create_model_component("scale2d", "mdl") >>> print(mdl)
Create a component of the scale2d model and display its default parameters. The output is:
mdl Param Type Value Min Max Units ----- ---- ----- --- --- ----- mdl.c0 thawed 1 -3.40282e+38 3.40282e+38
The attribute for this object is:
The amplitude of the model.
The functional form of the model for points is:
f(x0, x1) = ampl
and for an integrated grid it is:
f(x0lo, x1lo, x0hi, x1hi) = ampl * (x0hi - x0lo) * (x1hi - x1lo)
This later case will only be used if the integrate attribute is set to True .
