tophat2d(xy, x0, y0, r, a=1)[source]

For fitting a 2D tophat distribution.

Parameters

  • xy (numpy.ndarray) – Points to fit upon (x, y).

  • x0 (float) – Vector offset.

  • y0 (float) – Vector offset.

  • r (float) – Active radius of the tophat.

  • a (float) – Amplitude.

Returns

z – Tophat fit evaluated at all (x,y) in xy.

Return type

numpy.ndarray
