Incomplete Landsat 8 images

[chlsl]

Sometimes the images obtained with get_landat.py are incomplete.
For example the command

python3 get_landsat.py --lat 35.96 --lon -96.79 --start-date 2020-04-15 --end-date 2020-05-13 --band B4 -o tmp

downloads the following images:

Thanks to your explanations @carlodef, I checked the Landsat 8 tiles for these coordinates. The tile 27/35 should be preferred, but the images downloaded are from the 28/35.
