Summary

RawDataDiff is just a special case of ImageDataDiff where the images are one-dimensional, and the data is treated as a 1-dimensional array of bytes instead of pixel values. This is used to compare the data of two non-standard extension HDUs that were not recognized as containing image or table data.

Extended Summary

ImageDataDiff objects have the following diff attributes:

diff_dimensions: Same as the diff_dimensions attribute of ImageDataDiff objects. Though the "dimension" of each array is just an integer representing the number of bytes in the data.
diff_bytes: Like the diff_pixels attribute of ImageDataDiff objects, but renamed to reflect the minor semantic difference that these are raw bytes and not pixel values. Also the indices are integers instead of tuples.
diff_total and diff_ratio: Same as ImageDataDiff.
