pynrc.reduce.ref_pixels.mask_helper()

Helper to handle indices and logical indices of a mask

Output: index, a function, with signature indices = index(logical_indices), to convert logical indices of a mask to ‘equivalent’ indices

Example

>>> # linear interpolation of NaNs
>>> mask = np.isnan(y)
>>> x = mask_helper(y)
>>> y[mask]= np.interp(x(mask), x(~mask), y[~mask])
