All Reproject functions output NaN

[namanbajaj2501]

Hi,

I have been trying to use reproject to project PACS160, SPIRE250 and LABOCA images to SPIRE350. Reproject works fine for SPIRE250 to SPIRE350, but gives out NaNs for the rest. Additionally, It worked fine for me few weeks back, but now, with the same commands, it doesn't seem to. The commands are as follows.

from reproject import reproject_exact
hdu1 = fits.open('g326_350_cut.fits')
hdu2 = fits.open('g326_160_convolved.fits')
result1,result2 = reproject_exact((hdu2[0].data,hdu2[0].header),hdu1[0].header)
fits.writeto('g326_160_reproj.fits', result1, hdu1[0].header, overwrite=True)

The output fits file has NaNs and result2 contains zeros. I have also attached a pair of fits files. @astrofrog
