These models take as input x and y arrays.
These models perform simple mathematical operations.
Const2Dmodel returns the constant replicated by the number of input x and y values.
These models provide shapes, often used to model general x, y, z data.
Planar2Dmodel computes a tilted plan with specified x,y slopes and z intercept
These models provide profiles, often used sources in images. All models have parameters giving the x,y location of the center and an amplitude.
AiryDisk2Dmodel computes the Airy function for a radius
Box2Dmodel computes a box with x,y dimensions
Disk2Dmodel computes a disk a radius
Ellipse2Dmodel computes an ellipse with major and minor axis and rotation angle
Gaussian2Dmodel computes a Gaussian with x,y standard deviations and rotation angle
Moffat2Dmodel computes a Moffat with x,y dimensions and alpha (power index) and gamma (core width)
RickerWavelet2Dmodel computes a symmetric RickerWavelet function with the specified sigma
Sersic2Dmodel computes a Sersic profile with an effective half-light radius, rotation, and Sersic index
GeneralSersic2Dmodel computes a generalized Sersic profile with an effective half-light radius, rotation, Sersic index, and a parameter to control the shape of the isophotes (e.g., boxy or disky)
TrapezoidDisk2Dmodel computes a disk with a radius and slope
Ring2Dmodel computes a ring with inner and outer radii
