Bases: FloatTestCase

Inheritance diagram of astrowisp.tests.test_piecewise_bicubic_psf.TestPiecewiseBicubicPSF

Make sure the PiecewiseBicubicPSF class functions as expected.

setUp()[source]: Define a set of picewise PSF grids to use during tests.

test_linear()[source]: Test PSFs that is are linear functions of x and/or y work.

test_one()[source]: Make sure that a PSF = 1 everywhere within the grid works.

test_pi()[source]: Make sure that a PSF = 1 everywhere within the grid works.

test_random_single_patch()[source]: Test PSFs equal to random bi-cubic polynomials.

test_zero()[source]: Make sure that all-zero input produces an identically zero PSF.

astrowisp.tests.test_piecewise_bicubic_psf.point_in_grid(point, grid)[source]: Return True iff the point is within grid.
