I don't see any datamodel doc for the SV0 coadd files but I notice that fibers in the BRZ_* arrays are not sorted in order of increasing FIBER number, so permuted relative to arrays in (C)FRAME files…

The following example shows that if a NaN value is present in the original data being compressed, the whole tile will be NaN when read in again:

Calling `len()` on an empty (i.e. newly created) FITS adds a HDU:
```py
>>> fits = fitsio.FITS('new.fits', 'rw')
>>> len(fits)
1
>>> 0 in fits
True
>>> fits[-1]
file: test.fits

I have a use case where I'm trying to perform some slicing:
```python
fits = fitsio.FITS('myfile.fits', 'r')
image_hdu = fits[1]
cutout = image_hdu[10:60]
```
The `myfile.fits` contains `BZE…

I'm evaluating `astrogo/fitsio` for scanning the header units of hundreds of thousands of FITS files. I'm not interested in the contents of the data units.
I noticed that the method [DecodeHDU](htt…
