2D Models

These models take as input x and y arrays.

Operations

These models perform simple mathematical operations.

  • Const2D model returns the constant replicated by the number of input x and y values.

Shapes

These models provide shapes, often used to model general x, y, z data.

  • Planar2D model computes a tilted plan with specified x,y slopes and z intercept

Profiles

These models provide profiles, often used sources in images. All models have parameters giving the x,y location of the center and an amplitude.

  • AiryDisk2D model computes the Airy function for a radius

  • Box2D model computes a box with x,y dimensions

  • Disk2D model computes a disk a radius

  • Ellipse2D model computes an ellipse with major and minor axis and rotation angle

  • Gaussian2D model computes a Gaussian with x,y standard deviations and rotation angle

  • RickerWavelet2D model computes a symmetric RickerWavelet function with the specified sigma

  • Sersic2D model computes a Sersic profile with an effective half-light radius, rotation, and Sersic index

  • TrapezoidDisk2D model computes a disk with a radius and slope

  • Ring2D model computes a ring with inner and outer radii
