Hey,
so where the Daniels manual uses the term 'serializing' (for the bits
that make up the LCW) this simply refers to the process of turning the
72 bits into 6 hex bits? And this is done in the same way for the
data information in the HDU even though it is not explicitly called
serializing in the HDU section of the manual?

Thanks!
