| Allowed Value | Details |
|---|---|
| flat | When applying packed or packed_v2 compression on an array that treats the entire image as a single line set the maximum number of bits for an offset to 65 bits. The flag is included for compatibility with software prior to CBFlib_0.7.7, and should not be used for new data sets. |
| uncorrelated_sections | When applying packed or packed_v2 compression on an array with uncorrelated sections, do not average in points from the prior section. |
