* Many of the bits are arranged so that given a flags word, you can
|
||||
* look at the values for the data point 0, then shift the flags
|
||||
* word right by 3 bits and look at the same bit positions to see the
|
||||
* values for data point 1.
|
||||
*
|
||||
* The #defines below help a bit with this; say you have a flags word
|
||||
* f, you can do things like
|
||||
*
|
||||
* (f & T1_SIGMA_THIS)
|
||||
*
|

* to see the significance bit of data point 0, then do
|

*
|

* ((f >> 3) & T1_SIGMA_THIS)
|

*
|
