This might be somewhat nit-picky, but I think that the parameters should be in the reverse order to match the style of other pcv writing functions that generally have the img data first, followed by the filename. |

Would going beyond checking if the dimensions are the same to see if some of the values are the same be helpful? Or is just checking that they're the same shape usually sufficient

That is a good question. We could check some values or also verify that it's the exact array. I think it depends on what can go wrong. Since the array is vectorized and written as a binary array, in order to have the correct dimensions the data type and the interleave format should be correct.

Ok cool, would just a simple assert np.array_equal(array_data.array_data, rand_spectral_array) be good or do you think that would take up more time than it's worth?

I think both ways are good options
