noctua.utils.analysis module

Analysis-related functions

class noctua.utils.analysis.EllipticalMoffat(amplitude=2000, x_0=0, y_0=0, fwhm_x=9, fwhm_y=9, alpha=5, theta=0, **kwargs)

Bases: Fittable2DModel

From: http://www.aspylib.com/doc/aspylib_fitting.html

alpha = Parameter('alpha', value=5.0, bounds=(None, 10))

amplitude = Parameter('amplitude', value=2000.0, bounds=(0, 65535))

static evaluate(x, y, amplitude, x_0, y_0, fwhm_x, fwhm_y, alpha, theta)

Evaluate the model on some input variables.

fwhm_x = Parameter('fwhm_x', value=9.0)

fwhm_y = Parameter('fwhm_y', value=9.0)

param_names = ('amplitude', 'x_0', 'y_0', 'fwhm_x', 'fwhm_y', 'alpha', 'theta')

Names of the parameters that describe models of this type.

The parameters in this tuple are in the same order they should be passed in when initializing a model of a specific type. Some types of models, such as polynomial models, have a different number of parameters depending on some other property of the model, such as the degree.

When defining a custom model class the value of this attribute is automatically set by the ~astropy.modeling.Parameter attributes defined in the class body.

theta = Parameter('theta', value=0.0, bounds=(-1.5707963267948966, 1.5707963267948966))

x_0 = Parameter('x_0', value=0.0)

y_0 = Parameter('y_0', value=0.0)

class noctua.utils.analysis.Moffat2DXY(amplitude=2000, x_0=0, y_0=0, gamma_x=9, gamma_y=9, alpha=3, **kwargs)

Bases: Fittable2DModel

alpha = Parameter('alpha', value=3.0)

amplitude = Parameter('amplitude', value=2000.0, bounds=(0, 65535))

static evaluate(x, y, amplitude, x_0, y_0, gamma_x, gamma_y, alpha)

Evaluate the model on some input variables.

static fit_deriv(x, y, amplitude, x_0, y_0, gamma_x, gamma_y, alpha)

gamma_x = Parameter('gamma_x', value=9.0)

gamma_y = Parameter('gamma_y', value=9.0)
