cwitools.modeling.sersic1d

cwitools.modeling.sersic1d(params, r)

1D Sersic profile in the form f(parameters, r)

I(r) = I0 * exp(-b_n * (r / Re)^(1 / n)) where b_n is approximated as (2 * n - 1 / 3)

Parameters:

• params (list) – Model parameters (I0, Re, n)
• r (numpy.array) – Model input

Returns:

The Sersic model

Return type:

numpy.array
