Hi.
I am trying to align two images I downloaded from MAST HST portal. For
this, I am using astropy-reproject package. However, I am running into an
error, every time I use reproject, despite providing the WCS information.
Following is the error:
ValueError: an astropy.io.fits.HDUList is required for Lookup table distortion.
I am using reproject version 0.6, and astropy both versions (3.2.3 and 4.0).
Information about the images: One image is from HST/WFC3 and second
one is from HST/ACS. I am attaching the two images along with my
reproject code (.ipynb). Please let me know how to proceed and solve
this issue. Thanks in advance.
