I am trying to obtain the statistics of an image that all pixels are equal to nan. While this a strange case and the input image is obviously wrong, Statistics should give a consistent result as an output: nan values. Otherwise in a general pipeline where this situations could happen, it crashes. This is actually the current problem I am having with the following error:

aststatistics: img.fits (hdu: 1): all elements are blank

Maybe a warning to show that all elements are blank/nan is good. That warning could be disabled with the option '--quiet' while keep giving as an output nan values. Does it sound reasonable?
