nanmedian3D

stcal.outlier_detection.median.nanmedian3D(cube: ndarray, overwrite_input: bool = True) → ndarray[source]

Compute the nanmedian of a cube.

This produces identical results to np.nanmedian but is much more memory efficient for large cubes.

RuntimeWarnings reporting “All-Nan slice” will be ignored.

Parameters:

  • cube – 3-dimensional array. Will be modified in-place if overwrite_input is True

  • overwrite_input – Passed to np.nanmedian, if True the input cube will be modified

Returns:

2-dimensional computed median array

Return type:

np.ndarray
