Yes Im running a local version of the website.
Im using the docker image "dam90/astrometry" which is more or less a clone of the "dstndstn/" image.
I ran an ipython console and executed the method uncompress_file("testdata.fits.fz","testdata.fits")
and logging resulted that the file is not compressed.
DEBUG:File: "FITS image data, 16-bit, two's complement binary integer"
Logged from file image2pnm.py, line 97
DEBUG:File is not compressed: "FITS image data"
but when I open the file with astropy.io.fits
it states that it is of type astropy.io.fits.hdu.compressed.CompImageHDU
I dont know what to do...
